Some new people leads

My brother gave me the name of a person at Partnership for Parks in NY who worked on green-grassroots efforts there and has some stories to tell about what worked and what didn’t.
My friend at Yahoo tells me that Yahoo Personals is one of the companies big moneymaking successes and that has about 40% of the market and YP has about 35% and the rest have single digits. He says he can put me in touch with the person in charge of Yahoo personals, as well as someone who deals with Yahoo Groups, which seem to be the first choice of a lot of grassroots organizers as a very quick and easy way to set up a mailing list, archive, database, and list of files and links.
Finally, I need to follow up again with Ed Cone. I know we’re now talking about me not using a coauthor so I need to go back and see if he really doesn’t have the time to help out, as he implied might be the case.
I haven’t heard from Danielle yet, btw, so I don’t know whether a financial offer has been extended to me yet from Sybex.
I’ve been spending the last few days sorting through names and sending out preliminary contact messages. I’m aware that I have a chapter due Tuesday, and as long as I can get a grip on what the overall message of the book is (I’m still not really sure what is the essence of what works for community organizing and what doesn’t, or what it all boils down to), I don’t see a problem getting a draft of the short-ish (10 pp. +) first chapter in by then.
