I found this on YouTube after following a Twitter Feed to first of all this blog post

quote from above…. “As a knock-on of this there’s been a large amount of media buzz about the use of Twitter as a mob-sourced geo-mashup generator to show snowfall.  Twitter users have been posting the first half of their postcode, plus the amount of snow in their location. 0 = no snow, 10 = bucket loads. ie: “#uksnow W12 9/10″  Developers have been mashing-up that data.
