I was having a sit down with @msg a week or so ago and our conversation landed on how everyone is reading the same things, going to similar events, and generally thinking about the same ideas.
@msg called this collective thinking.
He posited that anyone who is thinking of building something right now should be aware, that at least a bundle of other people are thinking and planning the exact same thing.
I was talking to a friend this past weekend about a hack off LinkedIN I would love to see/build. One of the most important things on LinkedIN is when your connections change jobs. I want a tool that can track your connections moves and send you an email summary of them.
Collective thinking, I like it.
So, if you have a startup or product, get moving, because there are a ton of other people planning the exact same thing.
