When Google announced their new +1 feature, which enables end users to recommend things, I was mainly struck by the incredible geekiness of it. Everybody understands “Like,” whereas +1 was taken from the Apache open source community and its history probably isn’t known to even 5% of Google’s users. Kellan at Laughing Meme digs into the history and finds what is, perhaps, the first mention of +1 style voting. I love it.
