Nice idea! Your server crashed before I could test the site fully, but I did find a tiny css bug: http://imgur.com/kSliFCL (Chrome 40.0.2214.85 beta (64-bit), OS X Yosemite)
Hope it helps. I'm only writing this because I'd probably use the service if it gets more polish. Oh, and it would be nice if I could make my guides private, so that I could use the site not only for past journeys, but for planning as well.
I'll also add a private field as mentioned. For tags, would you want to tag both guides and lists or just one of them?
