I use onlywire(paid) for social bookmarking, the good thing is it runs in the background and does not interfere with your work. The downside is when i go back and check the report, some of the sites i submit to fail and i have to do that manually.
Do i get alot of backlinks? yes. Traffic ? Not really.

My onlywire seems to have stopped working? processing submitted pages? Anyone kno why?

Like they do submit but dont go to success or failed status

onlywire used to be awesome.. now it's a bit crap.
the software they get you to download is a pain in the neck!
I don't really use it any more. It's better off manually submitting
to Digg and stumble upon.

I used to use onlywire but I did not get a lot from it.... Now I'm using socialmarker.com.... It's a bit tiring on the start but after that, it only takes a minute to finish bookmarking my blog or site.....

I use onlywire for quick indexing and to vary my backlinks a little. They offer little to no benefit as far as ranking goes.

To make the most out of these social bookmarking services one will be better off spending time and interacting and participating in the social bookmarking sites to reap the viral traffic that can be had from social bookmarking.
