When I moved to Quito, Ecuador in 2005, I had no information resources other than an out of date Lonely Planet and the memory of a National Geographic article I had read about a decade prior. I was giddily terrified, arriving onto a continent I had never been, where I knew no one, and with very meager savings.
Yet I survived, and that seems like quite an accomplishment when I consider the lack of resources available at the time.
The world has changed quite a bit since then. Unless you are headed into the darkest parts of the Amazon or deep into the mountains of Central Asia, every village you visit will have all the information you need to know online and available for you before you arrive.
