What i was thinking if social networking sites talk about interopability why cant they try to integrate trip planning services of new travel portals enabling them to double up as travel requirement or planning service provider. Example Orkut.com Communities on a particular city can take advantage of information on where member is existingly and would show fares/deals to fly to destination or alternatively if someone is fan of “Cold Play” and item is added that they are playing in Austria. Based on dynamic information of users existing location show fares for travel to concert etc. As content is being generated by users lot of potential exist for meta tagging it and analyzing it for presenting travel options.
