Disqus, you have made me proud by launching a full public API. The details can be found here. If you read my previous post about the Automattic acquisition of IntenseDebate, you will notice I am a big fan of Disqus, and use it on several sites.
This move comes right after many started to lose hope for the commenting service. By opening their API to the public, Disqus has proved they will not just sit still while WordPress moves to have their own commenting system. Disqus has now made it possible that commenting can go mainstream into many sites that otherwise might have not found use for it by allowing developers to custom make tools that work on Disqus.
Personally I am psyched to see Disqus stay ahead of the curve. It is exciting to think what great tools and applications will be made using their new API. I will cover them as they happen!
