Something I didn't notice before, mainly because I don't post that many movies for encoding by Posterous, but Posterous encodes movies in a way that they are viewable in your iPhone (H.264 quicktime, I guess). I only noticed it because my wife was viewing a clip on her iPhone, and that was from a posterous link I sent her earlier (see the post below for the funny movie). I thought huh, I didn't send her a youtube link.. Nope, it was Posterous!
This is just friggin' cool! And with autopost extended to vimeo, youtube etc posterous is THE gateway for everything internet.Thanks guys!
Edit: I should have checked the official posterous blog, since they just announced this.. d'oh!
