FriendFeed
Echoing Omar's post, I started using FriendFeed to aggregate my activity across various sites on the intertubes. I'm at hyperionab on their services. It's quite cool. I have this blog, delicious, Facebook, Google Reader, last.fm, LinkedIn, Netflix, twitter, and Yelp plugged in to it. It's really useful that I can flag something as shared on Google Reader and it shows up in my FriendFeed feed. They've done a great job of creating that Facebook style news feed that works to aggregate many services, not all of which are social networks.
