I was doing some research onto the top sites on Earth. Top 500 according to Alexa: Something bizarre - a few social networking sites nobody is talking about (well, almost nobody).

hi5.com
bebo.com
badoo.com
tagged.com

See if you can find out how to get people to share your site on facebook, too. Submit some documents to docstoc.com and that might help with google (not sure, but theoreticall it makes sense to me, though I can't explain it...oy).

Those are quite in addition to the normal social sites you do hear about (twitter, facebook, myspace, linkedin...).

Do you have your own profiles on those sites in the list above? (and are they all themed so anyone who searches for flash tutorials on the sites will find you automatically? Join all the related and decent groups you can in each.) Take on only one site a week, so you can learn the "rules" of each, and how to do stuff. See who are the most "liked" and most disliked, if any, in any group. It's valuable research that takes serious time, but will pay dividends forever once mastered.

Have you read the Attention Age Doctrine 2 from Rich Schefren? Great info there on why you want to do that, and more that I haven't talked about yet. It's amazing (IMO) once you get to page 35 and start with the steps of

1. Map your market.
2. Monitor your market.
3. Join your market.
4. Build your market.
5. Lead your market.
6. Sell your market.

He tells you more in there if you haven't read it. Read it, *at least* pages 35-44.

Stay great!
