> The problem with being self taught, at least in my experience, is that you end up being very strong in whatever areas it is that interests you, and whatever areas of CS are relevant to the projects you're working on day-to-day.

Which is not necessarily a bad (for whatever definition of bad) thing.

For the startups you worked at, your ability to write code was far more valuable than your understanding of underlying CS concepts.

Kudos to you for having the maturity to acknowledge the gaps in your education and to address them in a manner that complements your life.
