Twitter is, as we regularly point out to the 99% of teachers who don’t seem to use it yet, the world’s best CPD tool ever. As a way of connecting you instantly with top educational practitioners around the world there has never been anything like it.

What we used to say is that it was relentlessly positive and optimistic too, full of people who you would never meet, you could communicate with as best of friends even though you wouldn’t recognise them in the street, people who you could agree and disagree with in a spirit of profesional discovery.

What we are seeing now, though, is an encroaching nasty cynicism which we are finding disturbing. It’s not that you have to agree. It’s the spirit with which you disagree. Some new rule of engagement are needed we feel, so:

If you regularly criticise but do not have a blog or similar in which you are putting forward your own, alternative views, then *block*

If the spirit of your criticism is mean, snide and niggardly rather than professional and supportive, then *block*

If all you do is criticise, never anything positive, ever, then *block*

If you are clearly using Twitter’s anonymity to say things to people (whose name and face are brave enough to be there on display) that you wouldn’t probably say to them face to face, then *block*

If your sole purpose of being on Twitter appears to be to, ahem, wet the chips of anyone who is actually trying to make a difference just because you don’t agree with them, then *block*
If your version of an argument on Twitter involves ending a snide Tweet with the hashtag ‘#fail’ then a very big *block*
So, be angry, disagree, challenge, contradict, point out how everyone else is wrong but do it in a spirit that moves everyone forward and helps them be better at what they do, as professionals and as human beings.
