A Travel Blog will allow you to post "LIVE" accounts of your trips while you are on the road!  All you have to do is to find an internet cafe, sit down, sip your cup of coffee or glass of fine wine and type away.  

This is an absolutely fantastic way of recording your thoughts and feelings about your experiences.  I have a short attention span anyway when I'm traveling so this will help be a lot.  I can also post photos "live" on what I'm seeing and where I'm visiting.  This is a very cool way of sharing your experiences with friends and family back home.  

You can also use your blog to journal your PRE and POST trips thoughts and/or travel plans. 

I also use my blog as a creative outlet to write about things, events or just about anything that interests me when I'm not traveling.
