Who's an Angel, Super Angel, or a Micro-VC? Investor Nomenclature by @ManuKumar

This is a newbie question, so forgive me for that.

The article says that there are too many angel investors right now, so the available money exceeds the number of quality companies at the seed stage.

Here's the newbie question - where are these angels? Are there places people gather online, or is it all about running in the right circles?

How does a team of talented developers get connected to the funds they need to get started?
