NNW is a great program that makes reading RSS files and blogging a breeze. I can only see this program getting better and better with time. Like utilizing the Safari API when it’s available and every other improvement Brent adds.
SpamSieve is a great product. It uses Bayesian filtering to recognize spam from non-spam. I like the way it works using my email client, PowerMail. I’m already a registered user of Spamfire but I don’t think I like the 2 application approach. That and I’m dependent upon Matterform to keep up with the filters.
