To Twitter or Not to Twitter

Just when I thought I was getting my head around online networking - www.ecademy.com, Facebook, www.theathenanetwork.com, the Beermat Entrepreneur (www.beermat.biz), this blog, ecademy blogs, a findaTVexpert.com Facebook group, etc - along comes Twitter. Apparently it allows friends to 'stay connected in real-time'. The mind boggles!
