No, I have not RTFA, but - I use twitter every single day but have only posted one tweet. I only follow a few interesting people but I now find it invaluable as a way of keeping track of them. I have stopped using facebook - I realise that I now am more interested in seeing what other people say than publishing my own content, I guess a lot of people are like that.

I made a simple suggestion of changing the headers to match the rest. Their reply was to change my resolution... have you ever made suggestion to a website that has been acted on, or have you received such sage advice as me?"
