Hi, dat maintainer here. I made the website in a couple of hours (https://github.com/maxogden/dat-data.com/commits/gh-pages) but have spent about 9 months on the code so far (read through e.g. closed issues for an example of the scope there). I also have tried to convey that dat is still pre-alpha and that people shouldn't use it unless they wanna get involved w/ early development, but someone (not me) decided to post it to hacker news nonetheless.
