Well - here we are at Linkedin. Weird - set up my account a long time ago, have a profile of sorts and following a few groups, but clearly it's not something I spend lots of time with. Remarkably I remembered my login. Will play with the 'add applications' when I have a bit more time.
Am wondering why I feel rather ambivalent about this tool.......hmmm. Maybe it's information overload, maybe it's just that I have too many fingers in too many pies.......... ........and just can't manage another deluge of information?
