I think one mention is enough. How many user names do you have?The blog isn't bad, but spamming the board is!
Not only is the spamming of the board annoying, but so is being dishonest about the fact that it's not his blog. If he was upfront about this (and not using multiple names) it wouldn't be as bad. It says alot about one's judgment if you can't be upfront about something as silly as starting a blog.
I just found a new blog that has the makings of really being a hit. So far there is a little content but the sponsor is a riot. Check it out at www.lawschoolblogger.com.
