Tell me when this blog is updated
If you don't use a news reader to scan blogs you like to read, and are an infrequent visitor, and want to know when your popular sites have been updated, this tool might be really useful. In other words once signed up for a site, this tool sends you an e-mail to let you know something new has been posted on your favorite sites.
Blogarithm lets you easily manage all the blogs that you track. Any time one or more of the blogs you read changes, you'll get a morning email listing all your blogs that have new content - including excerpts when available.
