Since it was winter again, I started reading more and then I found out we actually didn't have an activity stream
item for books that you've read.
Now we do. I added Good Reads to the list, as well as other sources of your (online) activity such as Identica (microblogging), Foursquare, Ravelry (for knitting!) and blip.tv, in addition to the ones we already had such as twitter, flickr, any rss-feed, delicious, etc.
