I think the best way is to keep a blog. You can run one on Wordpress.org, or use your own domain name and run wordpress. Then on Facebook you use networked blogs to link your blog to Facebook, so when you do a new post, it automatically posts a link to it on Facebook.
Then you can start a thread here on the forums and post a link to your blog entries to remind people here to read your blog.
Normally I write a trip report after a trip and post it in my blog, but in the last few years I have fallen behind, so instead I am posting each day in a thread here. Eventually I will condense it to a trip report and put on my blog.
Many people only write about their trips on Facebook but I don't think this is the best way to keep a travel journal because old posts are hard to find on Facebook.
You will probably want to be on Facebook while living in England so you can easily keep in touch with your friends.
That is my answer to this, others may have more to say.
