@bradenslen I also vaguely remember that, though I didn’t pay much attention to SEO at the time. Even now I don’t care that much about SEO for my personal site. For the moment I’ll let go of worrying about it, though it’s something I’ll keep in the back of my mind.
The tough part is that the way I’m doing it in CSS, it only works when viewing on my website as other sites, readers, and even browsers (depending on settings) will use different CSS and displays. So it won’t necessarily benefit everyone. I also spent a few minutes thinking about how it might affect accessibility, but I think that most screen readers will still see them as links and present them as such, so hopefully there are no problems there.
