The Mystery of the Cat Sticker I've had on a now-dead laptop (I was at some dev meetup and we did a sticker-swap) is solved! It's old tho, doesn't have yellow eyes.
Another day, another "bring back Google Reader" article that does not acknowledge Reader's extremely robust social features.
These features allowed someone to, for example, share an article they liked to their friends and spawn a private mini-forum to discuss that article. It was similar to sharing an article with friends on Facebook, but based on your RSS curation rather than whatever you got from Facebook's awful news feed.
