Come to think of it, there’s most likely not a single “solo” programmer in the world. Even the ones locked in dark cabins have are connected to zillion of other developers. We have Twitter. We have email accounts. We have blogs. We have forums. And we have loads of more ways to connect and ask help from each other.
Even if we “work alone” we aren’t developing things solo. There’s loads of people helping us when we just ask. (see for example here – I was pretty amazed to see so many helpful replies).
