Jim sez, "MyStack.com lets you build Stacks – self-updating link lists that you can paste into your blog or web page. You can build a Stack that lists all the posts which link to your site, or a Stack that lists every message talking about a particular topic. MyStack.com uses PubSub's matching engine to match blog entries and newsgroup posts against your request in real time. That means that any time you look at a Stack, you're looking at the most recent set of links – we rebuild the Stack and rewrite the HTML for you, automatically."
(Thanks, Jim!)
