We have now got a blog. Please volunteer and post any suggestions on the new post; this post won't be checked regularly. The original text is kept below for completeness.
Blogs are very interesting things. They let us share content that doesn't fit with the question / answer format, and collect information that would otherwise be scattered around the internet.
If we get a blog, we need people to put stuff in it. So, if you want the blog and want to put content on it, please show your commitment.
