RSS+Aggregators

Web Based Aggregators

 * [|Bloglines] - http://www.bloglines.com/ (One of the first web based solutions, and the Art Guy's favorite.)
 * [|Google Reader] - http://www.google.com/reader (Ties in with everything else that requires a login with Google.)

Email based Aggregators

 * [|Feedblitz] - http://www.feedblitz.com/ (Can send digests of blog entries to your email inbox daily.)
 * [|Google FeedBurner] - http://www.feedburner.com/ (Feedburner is known more for providing statistics and poscasting support for blogs, but it does offer a way to subscribe to RSS feeds through email as well.)
