My nerdy obsession of the hour: iStalkr, an RSS compiler that grabs feeds from various services you specify and plots the data therefrom on a timeline. I’ve got mine set up currently to combine the books I’ve finished reading, posts I make to my weblog, twitter messages I post, bookmarks I plop onto del.icio.us, photos I post to Flickr, and movies I rent from Netflix. It makes for an interesting combined view which I’m sure will come in handy for a reference while writing our Christmas letter this year. You can see my timeline here.
