I'll ignore MyVidoop since it's a complete usability disaster.

As for Ian's OpenID provider hack, it's actually a nice proof-of-concept/hack.

@johnnytanned Try it, you appear to be defending the traditional login method over openid and that's a dead-end for you.

OpenID by default still relies on the traditional user+pass, but only a single one, instead of one-per-service, and this hack is a cute, cool, great, awesome, fking awesome one( notice the gradual satisfaction increase ), 'cos it completely removes the old method, replacing it by a simple 5-digit token you get "IM, SMS or your favorite Twitter client".

As I said, try it, comment later.

The only downside is: Twitter's unreliable, has a 250 sms-per-week limit and there are many uses for Twitter's sms notifications beside the official one. (like getting sms notifications of special emails, free, not device-specific & battery-friendly too unlike other solutions, ex: push mail)
