One other thought on Bloglines. (the blog aggregator that I plugged in an earlier post). The interesting thing about these services is that they allow a reader to completely avoid the ads served up on blogs. That is, you never actually leave Bloglines' site -- they simply feed you the text from the blogger's most recent post(s). Most of the blogs I read don't actually serve ads. They're simply using the forum as a way to generating interest and eventually selling more of their product or service. But for those bloggers that are generating substantial revenue by serving ads, these services present a big challenge.
