My concern is that too much Facebook terminology is placed in the Boonex product. For example, "Wall" is a trademark of Facebook. Facebook is aggressively hunting TM and R violators. Any site acting as a social network that uses the registered trademark "Wall" in the same or confusingly similar function as how Facebook applies "Wall" can be sued.

I haven't found any registered trademark for "Like" but that doesn't mean that Facebook hasn't listed it as see more an unregistered trademark (TM) instead of (R).

Facebook vs. Teachbook is an example on how aggressive they are getting suing Teachbook for the use of "book". They already claim "Face".

Another concern is their patents. Using "Like" as a method for voting.

Just a thought.
