Page Rank

I have a blog on Wordpress at http://calcuttaglobalchat.net. Few months back I had PR 3. Suddenly I found that my PR drop down to 0. I panicked and had long discussion on Google Adsense Support forum. They said it is OK to use text link ads as long as you have “NO Follow” attibute for the links.

The good thing is the drop of page rank did not affect me site search engine positions. It is still doing as good as it used to do.

Only thing I am not sure is the adsense income. My income has been pretty low for the site, but low for a long time now. Not sure if it has anything to do with the Text Link Ads.

If there is anybody out there with some knowledge on Text Links Vs Adsense income, please share with us.
