I think thats great and one of the most recommended ways to get free targeted traffic to your website or blog.
There are many excellent ways to develop targeted traffic through Facebook; however, be as transparent as possible. Facebook is better leveraged being transparent.
I would like to know also. I have heard of people being very successful on Facebook. I tried it but found the process hard to master and frustrating. Anyone have any good tips for FB?
As long as you do it right, it works out great. If you don't do it right it is more or less useless though. I would suggest using software to help add friends, then work on creating closer contacts with those that take kindly to it.
Using facebook is the same as myspace, you need to build up your friends lists. So on facebook you can "invite friends" to facebook from your other sources. Or you can click on "groups", join a group that is of your interest, and then become friends with the members in the group. But don't just spam people. Remember, you are supposed to be there to be a part of the community, not to promote your product, so make sure you join in the discussions etc...and then over time discreetly let people know about what you are doing.
