A regular commenter on this site has suggested I institute a Daily Post open to anyone with something “intelligent, reasoned and non-vitriolic” to say about the issue(s) of the day. (I’m replying to him here because I have no other way of making contact.) I can see why the idea appeals, but it would change the character of this blog and potentially take it in a direction that I never intended. Besides, the job of moderating and editing contributions could take more time than I’m prepared to commit. So thanks, but no thanks. I'll continue to publish the occasional guest post, as I've done today, but not on an "all comers welcome" basis. The way is open for anyone else to start a new blog along the lines suggested.
