On my previous trip I tried hitchhiking for the first time and became addicted so this year I'm spending six to twelve months traveling in East Asia and Eastern Europe.
I also tried couch surfing for the first time on my last trip and had a great experience in Budapest.
But then I ran into a problem...
When you're hitchhiking you never know if it will take a couple of hours or a couple of days to get to the next place. Or sometimes you're trying to get to one place and a driver offers a ride to another good place when nobody was going to your planned place.
Since the couch surfing website doesn't list peoples' phone numbers for obvious safety reasons and most people don't check their couch surfing account every hour or even every month it can be hard to hook up when plans are really vague.
Have I missed some obvious way to use the facilities offered by couch surfing? Is there another service that works better for vague wandering travellers to surf couches? Is there some equivalent a bit more like a chat room or such where I can tell an online travel community roughly where I'm going and get couch offers rather than writing to each person individually which is the only way I'm aware to use couch surfing?
I should've mentioned that I don't have a phone. It just wouldn't fit into my budget. I do have a netbook so sometimes I manage to find a free wifi hotspot and sometimes a local friend might give me a broadband dongle but most often I only have connection at accommodation and sometimes in cities.
