Travels publishing and sharing experiences and knowledge is set to expand even more than now next year.

A site aimed at frequent travellers, called Dopplr.com, is tipped to become a favourite. Users type in their travel schedules and link to their friends and colleagues. It allows them to keep track of where they are in the world and enables them to meet up in unexpected places - or watch for who is turning up in their home town in the next few days.  This sounds a bit like WAYN but is perhaps a little more selective.

Another site expected to boom next year is Twitter.com, which lets users text-message large groups of people simultaneously for free. The text is limited to a few sentences, leading Twitter's creators to call it "microblogging".

Seesmic.com - a serious version of YouTube will focus on "conversation" between individuals posting video diaries.  This is bound to attract a lot of travel blogs, strangely founded by Loic Le Meur, the internet advisor to Nicolas Sarkozy, the French president.
