no don't do that. if you are solo, you need to be focussed on what you are building. Creating something of HN scale would consume you and if you just want a community for few people, just add them to a mailing list or something.
This particular line of discussion prompted me to create a subreddit for us solo founders. Check it out at http://www.reddit.com/r/solostartups/ if you'd like to join in. I may be the only person posting there, but maybe others in the same boat I'm in will join in as well and we can all support each other through running a startup (or side project) all alone.
However, I don't want to stay solo. I have been solo for two years. It's too much work and not as fun as a partnership.
Building a community is a long-term investment. It will give me a wider range of resources and opportunities.
Plus, I have often found that I become more creative, focused, and generally better at things when I interact with other people periodically, even with regular non-hacker-founders (alone time is important too of course). I imagine having a social circle of smart entrepreneurs will be exponentially more beneficial to each individual. Y-Combinator is so sought after because of that social aspect.
Great products are nice, but great friends are even better.
