Are you tagfooting?

It's quite seldom to come across technology online that REALLY gives one that "aha moment" and i had to devote this short post on a social bookmarking site called tagfoot.
I'm always "Nit-picking" on User Interfaces(UI) but i feel that the designers of this social bookmarking site have done a great job for a beta - It has definitely enriched my experience online.
I can easily see this social bookmarking tool becoming one, if not the best social bookmarking site online. Check it out on youtube: Can your bookmarks do this?
Tagfoot is currently (Jan 2009) only accepting new members via invite.
I'm always looking for cool people online to share knowlege with and learn from - not just in my field of interest. Isn't that how cool communities and knowledge pools are built :-)? You can join me here if you want. See u there.
