When I was surfing for information about Cinque Terre, I stumbled upon an interesting site. It is a Wiki kind of site and depends solely on user input.
WikiTravel.org is a very useful site for all of you travelers, surfing for up to date info about your next travel destination.
It was inspired by Wikipedia, the free encyclopedia, and by the needs of travellers for timely information that long book-publishing cycles can't seem to meet.
Feel free to contribute your bit. I have already added a little piece of information to its vast and fast growing database. At the moment they have more then 18.000 destination guides and other articles written and edited by Wikitravellers.
I believe there is a bright future ahead of this project. In a couple of years we can expect various portable devices that enable Web surfing and navigation will become quite widespread. At the same time we can also see all kinds of wireless networks spreading all around us.
Put those things together and you don't have to be a visionary to see which way this is going...
I predict that in about five years time electronic PDA devices will replace classical guidebooks for travelers in the better developed parts of the world. The only limitation I can see is the non-existence of wireless networks in some parts of the world. For those countries a paper travel guidebook will still be the only option for quite some time.
