I knew that the University was considering adding FeedBurner to our Google Apps, but it would seem that it has finally arrived. If you are already logged into your Google Apps and you go to http://feedburner.google.com, it should pick up on your credentials and sign you into the Apps version. Perhaps soon we will see FeedBurner as an option on our Google toolbar (Mail, Calendar, Docs, Sites, Contacts, More...)
With FeedBurner, you can claim the feed on your blog (http://blog.lib.umn.edu/your URL/atom.xml), then install FeedBurner's Email Subscription widget on your own blog. This allows your readers to get a daily digest of updates to your blog by email. It's an alternative to using MTNotifier, a UThink plugin for email alerts.
