The first, which is very much a development of their previous work, is HearFromYourMP.com which, in keeping with its Ronseal-like name, aims to allow you to hear from your MP. Its objective is to facilitate dialogue between MPs and their constituents by getting people to sign up to a list which is only activated (for constructive debate and q &a) when the MP replies. Which is when things could get interesting. I'm intrigued by whether this will work; some tech-savvy MPs will definitely give it a punt, but I'm sure others (such as the bloke at the top of the "league" at the moment) will run a mile.
They've also been trying to work out new uses for Google Maps, by the look of Placeopedia.com and YourHistoryHere.com. The former allows people to tie Wikipedia articles in to locations; the latter allows people to write little tit-bits of info and history factoids and tie that in to locations too. I'm sure there will be many more uses of this technology as we go on; indeed, one can see a day when organisations will use it to give a visual representation of their customer base, or for marketing purposes....and so on, ad inifinitem. In the meantime, have a look at these, and get involved if you get the urge.
