Adobe bought out LiveFyre and shut down the comments system for personal blogs, which is a shame because LiveFyre was a fairly good fit for commenting on this site.
It had its issues – the admin interface was terrible and never worked properly – but it loaded right onto the page, not in an iframe, meaning I could use CSS to have full control over the look of the comments.
Alas, Disqus loads into an iframe, so I'm stuck using their standard appearance. It's not terrible, it's just a bit different, and that's with my blog's fairly standard black-on-white theme.
One day perhaps I'll maybe make something custom, but for now Disqus will have to do. Propbably I should upgrade to a newer version of Ghost, too, but this one works fine for me and ugh the hassle.
