A few things, if liketu is going to be a totally new stand alone product, more on site information is needed. The about is pretty meaningless, along with the features. A top menu I feel is needed. A page of, (similar to your post here), is needed to really explain what liketu is.

The Features, need a descriptive page also. What are the features? What and how do I use the features? How do I create a community?

I know it is beta, but you do need a lot more information on the site and a place for people to find it. One example: Where is the comment edit button? Can comments be edited?
