I've become friends with Bob and the rest of the crew at PubSub and I just found out that not only have they revamped their website they removed one of my complaints: email registration is no longer required and you no longer have to click on a link in an email to activate an RSS feed for PubSub search. Time to revise my PubSub HowTo! Congrats to PubSub on making their service even better and easier to use!
