Two very different entities. Techmeme is about the news and that's it. Hacker News is about the community and how we as developers and designers think about the news. Hacker News is more about the community. Like today a random post about Windows 1.0 to 7's journey led to donations for the guy behind Trumpet Winsock. Very few communities have such a strong positive energy in them like HN. I have learnt so many cool things here and I am just 20 days old on HN.
