Adding a microblog

Bit of a site reshuffle going on this evening.

A couple of years ago, I added 'notes' to the site. This was essentially what the microblog is now: short updates without headings organised in a feed.

I've decided that I want to post more on this site and the microblog is a friction-free way to do that. But, as the microblog would contain a lot of noise that wasn't work related, I was keen to separate it from my design and dev posts.

Lots more to do but happy to put this live tonight after about an hour of work.
