As I stated earlier, I want to add a commenting service to my blog. I could use already existing Software, like Disqus or as self hosted service the Isso commenting service. But lastly I decided to write my own commenting service.
Since there is no such commenting service implemented in Haskell yet, I have to write my own. I chose the Yesod web framework as foundation for my project. It already has basic functionality, but because I have not implemented spam protection and moderation yet, I do not recommend using it outside of testing purposes. You can check it out at my git repository at Github here.
