I made this animated gif with BLINK, Microsoft's answer to Vine. Not quite a smooth sharing process.

So, there it is. I masked out the rest of the picture, so that only the rooster is looping.

The app and the interface is actually great, easy to use, and kind of fun.

The problem, at least on the Surface RT, came from trying to upload this gif to Twitter, both through the browser, and through the native app. Just wouldn't do it. Photobucket didn't care and handled it like a boss, both through uploading from its own Win8 app, and through the browser. Which is odd, since Photobucket is the photo sharing engine for Twitter, so something is up on the Twitter processing side of things.

Incidentally, BLINK is an app coming out of Microsoft's research arm in so.cl. Not only can you export your little 10 second or less creations as a gif, but you can upload them to BLINK in their native video formats.

UPDATE: Twitter no longer accepts animated gifs. From the troubleshooting support page:

Check your file type. Twitter supports JPEG, GIF, and PNG file formats. We do not support animated GIFs. All existing animated GIF images will be left as they are, but no new ones can be uploaded. [emphasis added]

So, this is user error, or more like, user ignorance. I would like to know when that changed.
