A few weeks ago, I asked people on various networks to let me know what the single best thing about being on Twitter was. This was in advance of a session that I was doing for a CPD day at school on Twitter. That day was today, and I had 2, 45 minute workshops with groups of colleagues to share how I use Twitter, as part of a wider INSET day.
Here's the document which collates the suggestions from colleagues and contacts from my PLN first.
