I like to follow the leader and Danny Sullivan being the leader of the SEM industry, I followed suit and migrated the RSS feeds on this site over to FeedBurner. Please let me know if the feeds are not working properly. Either leave a comment here or email me at barry AT rustybrick DOT com. All the feeds have been migrated or redirected (if not longer used).
Any other feed you have should automatically be redirected to one of the main feeds. I will add more features as I get more comfortable with FeedBurner. Also every third entry should have an Ad from Google AdSense or an other.
