Let's do the math. I personally have only 1800 twitter followers. But look what happens when I aggregate all the followers of my tribemates. If each of my tribemates share my post, suddenly I can reach almost 280,497 twitter followers.
Before Triberr, I would work on a blog post. Then copy/paste the link into a link shortener, and then tweet it to my 1800 followers. Now, with Triberr, the software automates the collection of blog posts from my blog RSS feeds into the Tribal stream and presents it to all my tribemates in all my tribes.
I can come back later and see how many members shared my post and even how many click-throughs happened. My tribe members are still new at this, so the share rate is still pretty low. But getting feedback from the click-throughs alone is invaluable. I can also quickly see how many people thumbed up my post.
Now Triberr does have a currency system called bones. A new user is awarded 100 bones. Because Triberr's owners want to virally extend its reach to new members, I can invite any new member by simply typing in their Twitter ID into the "Invite" button at the top of my page. New member invites are free.
However if someone is already a member of Triberr, i.e. has signed up before, then it will cost me 15 bones to invite this person to join my tribe. Triberr calls this an "inbreeding" invite. Obviously the system is geared toward finding new members rather than poaching existing tribes.
I'm chief of a new tribe called "Indie Author". We are indie authors who blog and wish to share our blog posts. If you're interested in joining my Tribe, post your twitter ID in the comments.
Funny thing. Because of Triberr, suddenly I feel like blogging more. I've got some great members of my tribe who are already avid bloggers. Will you join us? See you in the Stream!
