Last year I had a thread here going about the traffic from blog directories
http://www.greenguysboard.com/board/...ad.php?t=39331
and since then it seams nothing has changed in case of traffic blog dirs send. Directories mainly work in a top lists manor ... the more You send to them the better the chance You'll be listed in top places and get a decent return ... so if You don't have a steady outside traffic, like Your hubs, other pages, SE traffic, etc. You're bound to be buried down at those dirs.
My question is really more in a sense of who's giving You a good traffic return cause it's obvious You can't have good places/hits on/from all of the dirs ... or at least my blogs couldn’t do it.
