A startup feasibility question
There are a lot of things stacked against me, and I'm curious if people think it is worth the effort to go forward with my idea. In addition to the competitors, I have a full-time job, and the startup would require a lot of skills I don't currently have (I'm a software engineer, but the idea is very web 2.0ish and I've never used ruby/ajax and have only a basic knowledge of databases).
How plausible is it for a single engineer, working nights & weekends, with minimal web-programming experience, to launch a successful web service?
