I agree…
I have 2 profiles (1 personal and 1 work). It’s amazing how many affiliates I have come to ‘meet’ that I’d never met before just by getting a facebook profile, as well as other affiliate managers.
And I’ve found so many people that I went to school with that I lost along the way, or that I’ve worked with years ago.
I’d recommend it for business… Especially if you are involved in industries other than ours.. It’s awesome for advertising. I can’t tell you how many ads I’ve clicked on.
And the groups function is awesome too… Can’t say enough about it…
Plus, I know one of the guys working on Facebook and they have big things coming soon that may benefit us 
It’s only about 1/10th the size of what it will be.
