There used to be a post on "Social Justice" here. As I thought about it, though, I began to think it was out of keeping with the rest of the site. Hitherto, this was only more or less a record of what I/we were up to. I guess many, or perhaps most bloggers use their digital spread for sounding off about topics that interest them. I can't resist the pulpit either... but I can cordon it off in its own space.
So I've started a new page, "Opinion" - available from the links on the right. If you're interested.
