Should have done this long time ago. Feedburner.com was bought by Google and as a result my RSS feed urls have changed to:
Please update your RSS reader. Thank you for subscribing.
If you don’t know what RSS is or don’t use RSS, I strongly recommend you check it out. My favorite desktop RSS reader is SharpReader from http://sharpreader.net. It has an Outlook like UI and, when a new item comes in it slowly raises a light blue box, with summary line inside, in the right bottom corner of your screen, stays still for a few seconds (during which you can peek and decide whether to click on it for more), then slowly descends and disappears. You can customize the frequency each feed checks for new items, among other properties per feed.
If you can’t use desktop client Google Reader is probably the most popular web-based RSS reader out there. Just click the “Reader” tab at the top of your Google/Gmail account.
If you have many blogs you follow regularly, a desktop RSS client with notifications on new posts is, IMO, a must.
