I've been a member of joblesstrackworld since the summer when I wound up my own business. I'm getting nowhere with the usual job sites so have been spending a bit more time delving through LinkedIn to find people from my previous career (which ended 8 years ago).
Just wondering how people get on with finding work from there - do you aggressively go through their contacts and try to connect with those that look useful or is it the done thing to ask for introductions instead, do the groups actually work (they seem to be very fragmented) etc. etc. etc.
