Disqus was a disappointment. I last looked at it a couple of years ago, and found it to be serviceable then, but it seems to have taken a slide onto the slums of the web, and is now covered in ads and unresponsive web pages. Not the kind of image that makes me think they’ll value the privacy of my guests. But I’ve found a different solution…
Having had my web site hacked a couple of years ago, I abruptly lost all enthusiasm for running one, so after I locked it down, I took a few years to think about what to do. In that time, I’ve realized that for 98% of what I truly want my website to be, there is zero reason to give anybody access to changing the site from within the site itself. Even I don’t have such powers. And by not letting anybody change anything, the site can be remarkably secure against hackers. Not 100%, but much, much closer than any system that includes interactive editing features as part of the design.
