Spam!

 I've been getting quite a lot of spam comments recently, so have turned 'comment moderation' on as a temporary measure. That means any comments you make won't show until I've approved them. I'm not censoring what people say - just checking it's an actual response to my post, rather than an 'offer' for something none of us want.

The balloon in the photo is full of hot air, which seemed relevant to the post until I started trying to explain it. Still, it's pretty and that's generally a good thing.
