Shameless plug for FeedBurner
By sharps on Apr 28, 2006
Another benefit of FeedBurner is the way it simplifies the subscription process (ie. press the big orange RSS button, choose your RSS client and you're done).
By far the coolest thing about FeedBurner is that it doesn't cost anything :)
When I get time I'll take a look at FeedFlare - a way to make it easier for users to share posts through mail and tags - something I've been meaning to add to our Roller template for a while.
