I realise that I have not posted much lately. I tried an experiment to post every day and then only one day in a month and compared the traffic to see what difference it made. In the month that I posted every day, the traffic fell compared to the month before. Then I didn't post very much at all and the traffic fell at the same rate as the previous month. It is quite hard to know what to conclude from that, but I think that I will just post when I please and see what happens!
