This request originated via recent discussions on HN, and the forming of HARC! at YC Research. I'll be around for most of the day today (though the early evening).
For me, the biggest reason is the community and the people that hang out on HN. I mean how many places can you get Alan Kay to do an AMA of such high quality as this:
It’s a new account created yesterday. Alan Kay did an AMA here a while back+ with the username “alankay1” and occasionally posted elsewhere. That account’s last post was 7 months ago. Given that user “Alan-1”s style and content is similar, it seems likely that he created a new account after half a year away from HN.
If you want verification, maybe you can convince him to do another AMA =) I’m still thinking about his more cryptic answers from the last one, which is well worth a read. I think that was before Dynamicland existed, but I may be off.

Other reasons are simplicity and speed of HN site that makes it a breeze to only focus on the content. No flashy stuff.
