Interesting.

I am wondering how this is going to be better/different than a smart search engine, or a travel/review site that may be entrenched in its space for a long time and may have a lot of UGC around places.

E.g. A google or yahoo search on best coffee shops in San Francisco turns up a list, a map and links to sites like yelp with a lot of UGC. What would a user gain from using tripful? Just wondering.

Check out http://travellr.com/ too, it has been running for a while now.

Useful for when you want to learn about the places you will travel !

Sounds like a pretty cool idea, hope it goes far.
