Well, now it's blogs about blogs. Or rather, blogs about blogs have been on the increase for some time, and are a bit like people eating their own skin. To put it less vividly, they're the same as writers' magazines, where the topic is writing: by writers, for writers, a kind of catch 22 situation. Or am I just being over the top on this?
At least with other magazines, they're mostly about something else besides themselves: sports magazines are written by sports writers, mostly, rather than by sportsmen. Business magazines are written by business writers, rather than businessmen, or women. But writers' mags are written by writers for writers, like looking in the mirror and telling yourself how beautiful you are.
I must admit that when I first began to write seriously, by which I mean when I began to write with the aim of getting published, I devoured every writers' magazine and book I could find. "Devoured" may be more apt than you think, in view of what I've said above.
So would I write a blog about blogs? Only if they were interesting. What's happening however, is that people are writing blogs about how to write blogs. Surely part of the pleasure of a blog is that you don't have to be told how to write: you can write the way you always do - for better or worse. (If it's for worse, people will quickly switch off. There's nothing worse than a badly written blog; or one in which you wonder why the person is writing at all when their command of the language is almost nil.)
This is a bit of a ramble: it's late at night; I've been on the computer for quite some time composing music, and I need to go to bed...
Maybe I'll think more clearly tomorrow!
