I started using Friendfeed. I'm not sure about the functionality that it offers. I added a lot of services that I'm using on the internet. Now FriendFeed will collect all the different things that I do and write and create a new 'feed' of these. This can be an real feed or a page which shows all the items.
My feed can be found at http://friendfeed.com/pstuifzand. So if you are interested in what I'm doing, feel free to take a look at my feed.
