Everyone has an opinion, but is anyone going to listen to yours if it doesn't include a funky picture and caps lock? Hell no. That's why SUPER is here. It's an odd little app from Biz Stone (famous for co-founding Twitter) and his startup Jelly Industries.
SUPER attempts to make it easy to share your thoughts in just a few seconds with snazzy, image heavy posts. So you pick from an opener like The Worst, I Love, or Check Out, then add your text and sign it. Next, you start mashing a button that pulls up random background images based on your text, then another button that applies a random filter. You can also take a picture to use as the background.
The app seems kind of fun to play with, though sharing options for other social networks might be nice. As it is you're just sharing with other SUPER users. I don't see much reason to use the app personally, but maybe this is right up your alley.
