Feedburner for your blog feed, you should turn on Pingshot, a new service introduced yesterday by Feedburner: "When you use the new PingShot service, we will 'ping' a collection of services that you choose whenever we detect that your feed has new content."
To do that just login to your Feedburner account and click Publicize, then select Pingshot (on the left). I've ticked everything on that page (PubSub, Ping-o-matic, Newsgator) and clicked on the "Add one" dropdown for "up to four additional services" and added as many as I could. They only list 4 anyway so I added them all - Feedster, Icerocket, Weblogs.com and Tailrank (plenty of time to check occasionally in future if new ones have been added and if I want to change my list).
While you're at it you might select Awareness API on the Publicize pages too, and turn it on - "The Awareness API allows developers to build applications that can display, analyze and promote your feed's traffic data outside of FeedBurner". I've not had a chance to look into how much that's being used by external developers, but I figure it can't hurt.
I really like Feedburner. Their free service is extremely useful and well thought out and the support is excellent - friendly, helpful and prompt - especially on their support forums; and they keep improving their service and features all the time. This is the way a Web service should be run, and I hope they continue to go from strength to strength. Nope, I don't have shares in the company - if only!
(By the way, I'm assuming most people know about feeds generally - I've been thinking of doing a really basic "ground up" post on feeds and your blog, Feedburner etc. If that's something that would be of interest to you please let me know by a comment or email and if there's demand I may rustle something up.)
