Comments are a pretty vital part of any blog. It's one of the easiest ways to get feedback on whether or not your writing is resonating with anyone, and it turns out, thanks to Disqus, it takes roughly 2 minutes to add comments to just about any template-based blog.
Essentially, if your site is already loading a footer of some sort, just create a (Free) account, add their code to the footer, and you're done. Bing bang boom, like a boss, etc. etc.
I'm not sure why I hadn't thought about it until today, but I'm glad I did, 'cause comments have arrived!
