More signal, less noise: 10 Boston Twitter users worth following

I've been wanting to compile this list for a while, since people often ask me who are the "essential" Boston Twitter users worth following.

Worth following, of course, means something different to everyone, but here's my definition: their tweets are especially relevant if you work in the innovation economy in Greater Boston, and they maintain a fairly high signal-to-noise ratio. I've focused on individuals who don't work as journalists, but are in the front lines of starting, funding, and building companies here.

Basically, these are the ten people who give me a window into what's happening in a wide range of industries where Boston is a world leader.
