Well I’ve been on it a day but it’s very cool. It has all the support meebo.com has to offer in terms of instant messaging except more, since you can be logged onto multiple accounts. The pseudo OS is pretty neat too, very useful for organizing online files. However unless I’m wrong there’s no support for swf playback, and this would be a key feature, but apparently it’s still in its early stages.
Oh and fantastic multiple file upload support.
