Vodafone UK have launched a great Twitter and Google Maps mashup that lets users tweet where they’re going on holiday and have it automatically appear on their microsite map. The site also gives a trend analysis of what users are talking about in relation to their holidays.
Users just have to drop the '#ukhols' hashtag, their age, the first half of their postcode and where they're going into a tweet. All of this comes from the same guy that developed the #uksnow hashtag system that allowed users to tweet their post code and amount of snow, to create a truely accurate snowfall map, Ben Marsh.
The whole campaign is designed to promote Vodafone's drop in roaming charges this summer.
