I've recently finished reading How to Travel Full Time and Start a Freedom Business by Colin Wright on my Kindle. Throughout especially the former, he lists a number of useful (web) resources for people interested in full time travel. Since browsing the internet kind of sucks on a Kindle, I decided to collect all of these in one place here for others to use more easily.
I've omitted some of the obvious stuff (Facebook, Twitter, Google+, ...). This is a selection of stuff I found particularly useful, didn't know before or tend to forget about.
