Realizing that there a lot of folks who post awesome screenshots on Flickr end up NIPSA‘d… wouldn’t it make sense for someone to create a Flickr of Screenshots? I mean, hell, use Flickr as the backend and just aggregate semi-interesting uploads with the screenshot tag.
I mean, there’s a lot of potential use for this kind of thing — from software developers to designers to companies trying to get feedback and interface ideas. Anyone, anyone?

sounds interesting… I’m looking for an excuse to build something on S3 😉
Damn, if only I had a way to DONE.
Oh, wait, you wanted to search Flickr rather than create a completely new image-sharing app? Well, that a whole different kettle of DONE.
(I can combine ’em if you like. Feel free to throw other suggestions in too.)
