A few days ago I was developing a page for a client and one of the requirements was having a comment section in the blog posts, which made me wonder, how should I go about implementing a comment hosting service.
I did brainstorm for a while about implementing it on my own but then I had that feeling it would take some time because a lot of things would have to be taken into consideration like anonymous comments, nested comments etc.
As I am, I ended up looking for open source comment hosting services. First I wondered around the likes of Disqus and spot.im and then I started looking for open source alternatives. I was surprised by the amount of open source software available just for that.
Sergey Lisakov eventually has a whole page for just that. I have to say this page has it all, each and every open source comment hosting service and we can sort them by a lot of different categories. It's exaggerating in a way, like, which one should I use.
After a whole lot of Let me try this and I swear this would be the last one, I finally zeroed down on 4 of them which I think are the best ones.
