When we started our company, the facebook URL that matches our company name exactly (facebook.com/tinkeringlabs) was not available. So we used something close (facebook.com/tinkeringteam).
I recently found the person who had set up fb/tinkeringlabs, and he has given me control of that URL. So we could, in theory, move.
But, if we move to the /tinkeringlabs URL, we will have to get our audience to move, and for sure there will be some drop off. What do you think, is it worth it?
