Mashup Update
Here's a Mashup Update, the winners have been announced and they're both implementations with a similar feel and a relevance for Nestoria users:
Suburban Trends compares and contrasts suburbs on things like crime statistics, levels of acquired education, socio-economic standing and perceived safety standards,

and
Know Where You Live which aims give you as much information as possible about where you live, including historic photos, rental price data and various statistical data – the judges liked the citizen-centric 'common questions' section, which added to a user experience that could have been considered a little dull considering much of the data available at the moment is a bit on the dry side. This mashup was also created in 24 hours...what have you done with your day today...
