This is more of a job listing than an actual "blog" "post" per se.

You mention a few authors, but would you mind sharing specific books or other resources on community building you found practical and helpful?

Kawasaki I know, but who are Godin, Ries and Trout? Pretty sure "trout" at least will be an unproductive google search.

Godin is Seth Godin, who writes about online marketing and product development here:

http://sethgodin.typepad.com/seths_blog/

Many of his articles are immediately applicable to your start up, and in my opinion, are extraordinarily valuable.

Eric Ries writes about agile development and small start up culture/strategy here:

http://www.startuplessonslearned.com/

I have not read many of his articles, but my understanding is that he is making quite a name for himself as a start up guru.

Trout escapes me as well, I have not heard of him.

I guess Jack Trout is meant, an author of some marketing books: http://en.wikipedia.org/wiki/Jack_Trout

#1 Skill for successful community building: Hustle. If you can combine hustle (and bury any feelings of shyness) with some level of domain expertise, then you have a good chance of fanning an ember into a small flame. I've noticed this as I build and cultivate interest in UXForum.com. I relentlessly reach out directly to industry folks by email/skype/IM/phone/in-person to talk about what I'm building, how it will provide value to them and to generally sell them on the vision. You have to love doing it and you have to enjoy people.
