I like Reddit's /r/science (http://www.reddit.com/r/science http://www.reddit.com/r/science). You'll find some of the same articles as Hacker News, plus some great discussion from smart people who aren't necessarily computer geeks. For straight computer geekery, there's /r/technology (http://www.reddit.com/r/technology http://www.reddit.com/r/technology) -- but I like it less than Hacker News since the comments can be more immature. (There also seems to be a large population of gamers on that subreddit, and I'm not a gamer, so I have less in common with the people there than with many people here on HN.) For marketing and some general startup business advice, I like http://www.inbound.org/ http://www.inbound.org/ -- they are also starting to do AMAs ("Ask me anything") like Reddit does with well-known startup/marketing folks. For intelligent interviews with successful entrepreneurs, you can't beat Mixergy (http://mixergy.com/ http://mixergy.com/). Disclaimer: I've done two interviews with Andrew. Here's one I did on finding the right business idea, which might be useful to your less-technical-but-still-entrepreneurial friends: http://mixergy.com/course-cheat-sheet-find-your-biz-idea/ http://mixergy.com/course-cheat-sheet-find-your-biz-idea/ I also like http://www.reddit.com/r/IAmA/ http://www.reddit.com/r/IAmA/ and http://www.reddit.com/r/askreddit http://www.reddit.com/r/askreddit when I'm just ready to zone out and enjoy some Internet strangeness after a long day running a startup.
