I have finally got round to getting a permanent, lifelong domain name I am happy with (nicholaswilson.me.uk). When I bought nickcwilson.co.uk years ago, that was the plan then, but in the meantime I have learned to spell my name and .me domains have become available with the intention of personal use, precisely what I need.
My main reason for wanting a blog is to post technical things I work out. As any programmer can attest, the first thing to do when there is any sort of problem is Google it, and the results is more likely than not to be on a blog. Making a note of ideas as I get them on a blog is therefore a good idea. I will try to put other information up here too.
