Email. A posterous account to plan/log the journey (at least for now -- not sure if I will move it later). Hacker News of course. In other words: My expectation is that I will use a lot of the same stuff I use currently. But then I hadn't given a lot of thought to apps/socializing online. I am more focused on other questions, like how to support myself financially and how to address logistics (especially given special dietary and medical needs).

It's a shame there aren't more replies to this. I'm sort of weirded out to see the question, given my recent decision to do just that. :-/
