For KCA and all those who wanted Peekaboo comments in main page badly, Stephen has got it working! Avatar informed me about this and I thought I will inform my readers too. Instructions are in his post. There seems to be quite a few steps and so, apply the hack carefully.
Also, check out Gabriel Lau's nice hack to display a randomly chosen banner at the top in this post. This is one of the famous Wordpress plug-ins which is now doable with Blogger too!
