I bought a copy of Newsgator. Now that Newsgator online has become a free service, it was pretty much a no-brainer. I live in Outlook at work and use it heavily at home, so I love the fact that I can now synchronise my Newsgator subscriptions across the two machines. Posting direct to this blog from Outlook is another cool feature to which I've quickly become accustomed. And hey, with a little bit of help, you can even right-click in Firefox to subscribe in Newsgator - invaluable.
Remember the olden days when we had to spend hours paging through UseNet in the hope of finding something interesting to read? :-)
