It looks like the .com (http://twitvid.com) belongs to someone else, does anyone else see this as a pretty big hurdle to adoption?
Really well done, really well executed. The .com version might be dangerous, as people tend to type the .com intuitively, but these guys got the advantage of an early release...
Another one like this thats been live for a couple of weeks now.. http://tinyvid.io - much the same thing.
I don't fully understand...why not just post your video to Youtube and then tweet the URL?
