Or do you?
After holding out against Twitter and Facebook for ages, I've finally given in and joined up to the former. I'm in a new writers' scheme with the RNA and it looked like a good way of keeping in touch with people/making contacts. Plus it's supposed to be good for this building a platform stuff (which I know beggar all about, by the way, but I'm guessing it's nothing to do with decking ...)
However ... now that I've joined, I'm not really sure what I'm supposed to be doing. I've seen people tweeting the equivalent of 'I'm on the train' or 'Turned out nice again', but feel a bit silly doing the same. On the other hand, if you're supposed to be sparklingly witty or brilliantly clever in 140 characters or less, I'm sunk already
Or am I missing the point of it completely?
