On the previous platform that hosted my writing, Silvrback, comments were available by linking a Disqus account.

I've now moved over to write.as, and just about the only feature I was using on Silvrback that they don't have here is commenting (at least, not yet). As I was considering the switch, this initially gave me pause, but as I thought about it more I realized that, firstly, considering the very infrequent posting and thus tiny readership that I had commenting was in any case pretty much moot; and, secondly, in order to reduce spam, comment systems need to present some kind of barriers to commenting, all of which are an annoyance either to the commenter, the blog owner, or both.

Furthermore, as anyone who's read just about any comment forum anywhere on the web can attest, another big problem with commenting is the very small signal/noise ratio. Low-quality comments are easy and therefore ubiquitous, a problem that increases in direct proportion to a website's popularity. Genuinely high-quality, original and insightful comments, that actually add value to a discussion, are much more difficult, and thus far less common.
