This blog now has comments! Yai!

I used Isso (Official Website, GitHub) to integrate comments into this block. This was a feature which I missed dearly as I value the input from others, but wouldn't go all the way in using a Wordpress installation or similar blogging software.
Isso integrates nicely, just two small changes to my blogs templates and done. All comments are stored in a SQLite DB on this host. This means no data sharing with services like Discourse, Google or the like. Additionally this has the benefit that no registration is required. As I hate it when I have to create yet another account to just write one or two sentences of feedback. More often than not I refrained from commenting because of this.
Comments have to pass a moderation for spam reasons though.
