Startupping
Veteran entrepreneur Mark Fletcher has launched a great new resource for startups and entrepreneurs over at Startupping. It will be fun to see how this evolves - as more of a social network for entrepreneurs or an advice/howto for startups - probably some combination of the two.
I will try to contribute over in the Startupping forums frequently. I think Mark has created something here that has been sorely missing, and I'm sure it will prove to be a popular resource.
