The Next Wave of Photo Sharing Apps
vs. 
Looks like we're heading into the next wave of photo sharing apps with Slide and FilmLoop. Just like we're starting to see RSS get pushed down into the plumbing layer, we're also going to see p2p start to become more invisible and "just work". I think the next test of community apps will be "can I just install this on my parents' computer and just have it work and update?" I've been using FilmLoop (thanks for the tip, Eric) and I've been very impressed, even though it's still very beta and there are lots of kinks to work out.
