Anyway, the reason for this is lack of time and focus, so I've recently started creating accounts. So far, I have accounts at Stumbleupon, Digg, Propeller, Tagfoot.
As my time is short at the moment, are there any others that get good return for the time spent adding bookmarks? I realise I need to spend time making contacts to get the best out of these sites, so I need to concentrate on a select few to start with, and slowly expand the list as time permits.
Many thanks all.
