I also allowed my Flickr pro-membership to lapse last month, simply because I couldn’t remember the Yahoo login that’d been forced on me a few years ago.
I received a reminder to my normal email address, but when I tried to reset the login, the secondary email was apparently something different and probably another arbitrary Yahoo address that I’d never ever used, so at that point I gave up trying to give them my money.
I’m hoping Flickr will get some serious love now. I echo the calls to make it image-focused and inclusive. I agree with others about getting rid of the stupid, self-appointed ‘awards’ spam, and about speeding-up the site generally. I doubt it needs all of that browser-crashing, CPU-intensive javascript.
