Travel blog?

I've never really seen travel blogs.
Maybe they aren't really that popular with people from my age group. (I'm still young! alright!)

I've seen food blogs, which always makes me hungry and irritated.
I've also seen movie blogs, which is just like movie reviews that's on the net instead of on the newspaper.
I've seen many personal blogs that blogs about everything in their life, which sometimes includes traveling to other countries and stuffs. Are they counted as travel blogs too?

What's your view on travel blog?
To me, as long as it's blogged with real experience and not just some stories made about your "fairytale" dream getaway I think it's fine.

What about you? What do you think of travel blog?
Do you think some looks fake? Too hard for you to believe in? or looks just like an "walking" advertisement?
