What exactly is the use case here? I think this is trying to hard to be a new network of sorts without adding significant or desirable value. Below are some examples of online profiles that add value (outside of FB, Twitter, LinkedIn)<p>About.me provided a nice professional landing page for me.
Coderwall falls under a good niche to get actually valuable information
Threewords.me was super simple providing a throwaway fun.<p>GiveBrand.to requires an education system and is too professional to be like threewords. In other words, I still don't get why I should sign up for givebrand.
Can the user kill a tag? Do they have the ability to screen tags? For example, I can review a recommendation on LinkedIn before it's posted to my profile.
