It must be the time of year for "how to" lists.
Nick Denton has a list of the things you need to do a startup.
It's got the obvious stuff; Skype, Basecamp, Trillian, etc
But at the end, Nick gives me a very nice plug. I hope I can live up to that billing. It's too bad that I can't invest in every startup that follows Nick's advice. That would be fun, but I'd never be able to get anything done.
