I am not sure if know about www.triberr.com
. It is known as the reach multiplier and you have to be invited to be a part of the community.
I have invites if anyone is interested in joining my tribe, which posts your blogs or articles as a tweet to reach my followers as well. It has sent me great traffic.
My target market is business owners and entrepreneurs. I would like people who write to businesses, not necessarily about them. Please attach your blog address here so I can check it out and send you an invite.
Hope to hear from you.
