If you really want feedback, then I think the name 'LurnQ' is a very bad name for an educational website. I assume you are mis-spelling "learn", which just feels wrong for education (assuming you are trying to increase education!). If this is not what the name means, I apologise.

I understand that the twitter and facebook feeds may be full of content that you did not want, but you have not deleted it.

And all the content I have seen on there just does not belong on an education site at all: maybe I have a different idea of what 'education' means, but all of the content I have seen just doesn't match, in my opinion.

As for the format, it looks like a blog entry followed by blog-style replies. Which is mean to be the teacher? The format itself is confusing.
