Apologies to everyone who found this entirely obvious. I didn’t so maybe someone else will find it useful too.
I’ve just read Follow that… author and suddenly realised how the Topics bit of the reader works…
The post is about looking for authors (which I shall try out in a minute) but I’d only used the Topics column to do one-off searches for blogs to follow – I honestly hadn’t registered that they were still there, and if I click on them again, it is updated with new blogs on the same theme. I thought it was just a left-over list of what I’d done before… I get it now. Really rather too obvious.
Well, I did say I was slow. 🙂
