Hmm - really getting a bit behind here - it doesn't do to go on holiday; you have twice as much to do when you get home!
However, have 'liked' 23 Things on Facebook (not difficult...) and joined an online discussion yesterday evening (impressive...) A little disconcerting that the other 13 people seemed to know an awful lot more than me, but I picked up one useful tip to pursue. I found out about the discussion via Twitter - now Twitter has been the beginning of it all for me; it started my networking journey.
