When Microsoft has a perfectly good website for UK Education, why don't we just put everything there?
Well, the simple answer is that it is easy to update this blog as things happen, whereas the standard website takes a while to update because the information passes through the hands of many people before appearing. Whereas using this blog, we can tell you things straight away - and also we can tell you things that would only interest a few people. Which is what a blog is all about after all - micro-publishing for specific audiences.
It also allows us, and you, to offer opinion about things, rather than blandly stating facts. Let's face it, we all hear stuff that isn't supportable by statistics, research, facts etc - and some of the little factoids are much more interesting than bare facts. So the blog can celebrate them!
