You don't need great skills to make an impact. I work in Cambodia and there are plenty of opportunities for web developers to bring opportunities and learning here for the local culture. Also I would compare the existing base of developers here to what I imagine it was like in the US in the 70s. Computer Science is just picking up steam and the folks who learn it are very bright. Quite a cool climate to be in, in my opinion. Cost of living is dirt cheap, you have all the western amenities, and internet is fast enough (5 Mbit down via my phone).
