Social Networking Websites

I've been using MySpace as a medium for marketing several products & services and it's been going -ALRIGHT-
I'd really like to expand though, whether that would be to email marketing, forum advertising, blogs, or other social networks sites.

Anybody have success with anything besides MySpace?

I would take a look at marketing your products/services via the search engines--by getting building a good content site and then enjoying the search engine rankings and search engine traffic that come with it.

The products/services aren't directly provided by me, but me as an affiliate.
Would you still suggest the same thing?
