Contrary to the popular belief that the Heartbleed vulnerability was first discovered in March or April 2014, there's evidence that it was being exploited in November 2013, if not earlier. There's also a myth that Heartbleed doesn't affect users of Apple products, which is false; see Graham Cluley's Heartbleed OpenSSL bug FAQ for Mac, iPhone and iPad users for some basic factual information.
A handful of major news sites have put together small lists of Web sites whose users should change their passwords, but I've found these lists to be quite lacking, so I decided to put together my own. I've been compiling this list for almost a month; it's big, so it took a lot of time. This list includes some exclusives that I haven't seen anywhere else.
Given the enormity of this list, I strongly recommend that you search within this page for any sites you use, rather than trying to look through it alphabetically. Please note that there are several sections. Be sure to especially look at the first two sections; if you use any sites listed in those sections, you'll want to change your passwords for those sites (and anywhere else you may have shared the same password) as soon as possible.
If you search this article and can't find a particular site, see the section at the bottom of this article which explains how you can conduct your own Heartbleed tests. (Note that over a month after the Heartbleed vulnerability was disclosed to the public, over 300,000 servers are reportedly still vulnerable to Heartbleed attacks, so there's a decent chance that a server you use isn't on anyone's list, no matter how comprehensive the list may seem.)

Further Notes and Explanations
When I say "now's the time to change it," I'm making the assumption that the Heartbleed bug was fixed on the server prior to when the new certificate was reissued. Unfortunately, there doesn't seem to be a good way to tell whether this was the case, so we just have to trust that the sites did these things in the correct order. The worst that could happen is that the old certificate was either never revoked (and thus it's theoretically possible for there to be a MITM) or was revoked after the new certificate was issued (which would mean there was a window when MITM attacks could occur, or MITM attacks could still occur now if your browser isn't checking for certificate revocation).
The best practice with passwords is to have a strong and completely unique password on every site, and for this reason some prefer to use a trusted, secure password management system. You can either trust someone like LastPass or 1Password to manage passwords for you, or you could roll your own password management solution (for example, on Macs you could create a writable, encrypted disk image using Disk Utility and store all your passwords as folders on that disk, and unmount it whenever you're done retrieving a password from it). I recommend generating passwords with https://www.grc.com/passwords.htm (an alternative is https://lastpass.com/generatepassword.php but it's not my personal preference)
Also, when I say, "certificate appears NOT to have been reissued after Heartbleed publicly disclosed (although it might have been rekeyed while retaining the same date) - theoretically may be spoofable by a MITM," I haven't verified whether the old certificate was just rekeyed instead of being reissued (and I'm not aware of an easy way to verify this). According to Filippo Valsorda at http://filippo.io/Heartbleed/faq.html - "a certificate can be re-keyed without dates being updated, and many CAs are doing this." To clarify, "theoretically may be spoofable by a MITM" means that a third party between you and the actual site (a "man in the middle") could intercept the connection without you knowing it. Another possible attack that has been demonstrated is that a stolen certificate can be used in conjunction with an attack on DNS (e.g. a HOSTS file redirect or DNS cache poisoning) to enable a fraudulent site (for example a phishing page) to appear perfectly valid and legitimate to the browser (jump to about 1:20:22 and watch/listen until about 1:25:21 in Security Now 451 at http://twit.tv/sn451 or see page 7 of the show notes https://www.grc.com/sn/sn-451-notes.pdf).
Lastly, and I haven't seen anyone else discuss this yet, sites that are currently running Microsoft IIS or some other unaffected platform may have been running an affected version of OpenSSL sometime within the past two years, and it would be difficult to find out without directly asking the system administrators for each site (and hoping they respond; I'm surprised that major news sites like CNET evidently never got a response from several major companies). Obviously, that's a lot of work, but I'd guess that in most cases we can assume that if a site is running IIS now then they likely were running it prior to the discovery of the Heartbleed bug.

Test Pages - How to Check Whether a Site Is/Was Vulnerable
For many of the domains in the lists above (particularly those that weren't on a list of reportedly affected sites, as far as I knew), I first used the LastPass Heartbleed Checker first, and then followed up by testing with Qualys SSL Labs (or occasionally another site if I was short on time). For most of the sites that were already on someone else's list as reportedly vulnerable, I mostly just tested with SSL Labs to see if they were still vulnerable. If Qualys SSL Labs then identified a site as vulnerable to Heartbleed (which only happened a couple times), I double-checked those domains with Filippo Valsorda's Heartbleed test page for an additional confirmation.
Note that in some jurisdictions, scanning another site with one of these tools may be considered illegal. You may wish to check your local laws or consult with a lawyer before conducting any tests on a site you don't own. Remember, you can always contact the site's support and ask them whether their site has ever been affected by the Heartbleed vulnerability.
If you're testing sites on your own (especially domains not listed in this article), I recommend using LastPass Heartbleed Checker first, then Qualys SSL Labs second. To check e-mail servers (IMAP or SMTP), also use 1Password Watchtower third. If it isn't clear whether a site may have been vulnerable in the past, contact the site and ask.

https://www.ssllabs.com/ssltest/index.html (Qualys SSL Labs; comprehensive SSL/TLS tests including current Heartbleed status; lists certificate validity dates; does NOT include notes about past Heartbleed status of domains; also notifies if a site might be vulnerable to MITM attacks for other reasons)
https://filippo.io/Heartbleed/ (Filippo Valsorda's Heartbleed Test; only tests current Heartbleed status; does NOT include notes about past Heartbleed status of domains)

https://watchtower.agilebits.com (1Password Watchtower; some status messages and recommendations on this site can be a bit confusing, but on the positive side, this service checks Secure IMAP and SMTP servers on ports 993 and 465 (not just HTTPS on port 443 like the other sites); only tests current Heartbleed status; does NOT include notes about past Heartbleed status of domains)
UPDATE, 15 May 2014: Moved Bitly to the list of passwords to change immediately (the site was recently hacked, unrelated to Heartbleed). Added link to Robert Graham's recent finding that 300,000 servers are still vulnerable.
UPDATE, 21 May 2014: Added eBay to the list of passwords to change immediately (the site was recently hacked, unrelated to Heartbleed). Added PayPal to Known Safe section. Hat tip: Graham Cluley http://grahamcluley.com/2014/05/ebay-confirms-security-breach-users-asked-change-passwords/
