I enjoy the tech startup world and have plans to start my own in the very near future. Currently using various sites to learn to program myself (Codeacademy, Bento, Dash). I think it is important to know what your site is doing and be able to respond to issues.
I have learned so much from this community/site that I hope it will put me on a better path to success. However, the one thing about HN (and this is true of just about any community) that there are people here who are so smart, that I get convinced that I'm not ready to start building my site. I see examples of javascript here for example, and I think "My skills are no where close to that, how can I possible start working on my sites JS."
