That's interesting, I find myself in a similar position.

I like coding and I like to improve my coding skills and knowledge, but I feel I am more of generalist than a specialist, I am always lurking around HN, PH, IH, looking at products, trying to always get a little bit more about product strategy, marketing, design and UX.

I have considered a transition into a PM role but I'm still not sure I'm quite ready to step away from the developer role, a part of me would like to have an awesome project that I could build my own company around but I'm just not there yet either.

Either way, I'll be lurking the responses in this thread. Good luck with your move.
