And then I saw someone on my friends list complain that all her subject lines had changed and - oh. It's not the style. Huh. It's LJ-wide.
Around that point, I decided I didn't like the new theme anyway, and went back to the old one. It's comfortable and works, and I don't really need a tag-cloud.
And, probably because the link button is already there, the subject lines weren't changed like everyone else's. Which means that if I hadn't seen someone complain, I'd not have known anything at all. (This style has this function unnecessary in that one. Okay. Intersesting to know.)
