For some reason, some of the comments have been ending up in spam, which is something I haven't been checking frequently.
My apologies to those who may have posted comments which never appeared (they are there now). There were some really interesting comments that I wish had been posted. I'll start checking spam frequently and attempt to resolve this.
Also, for anyone interested, I am planning on changing the format/design of the blog, but I haven't settled on anything yet.
OK, back to the news!
