Firstly YES! Discourse looks amazing. Secondly, im here to flag a vote for open data access. I think if a post/thread/poll/anything is in a public forum/thread, it should be as public to other program’s “eyes” as it is people’s eyes.
I noticed the .json API is very broad and very cool … I hope this feature stays for the long-run (not just as a side-effect of the system being JS driven). Open (no-auth required, machine readable) data as well as open source is, imvho, hugely important to the web in preventing non-spiderable walled-gardens/silos such as FB/Twitter, encouraging innovation, integration and unlocking the potential of stored data from human interaction.
Just my 2p
