All sarcasm aside, this feature is absolutely the wrong direction. Github may have some things in common with social networks, but it operates on a longer-term scale. It's the difference between a book and a paragraph. People who care about this sort of daily minutia can find it plentifully on Twitter and Facebook. Github is great for finding out what people have been up to, without caring about what they're doing this second, and that's what was great about it.
