There are quite a few Twitter/Google Maps mashups available, but up until now I haven’t come across a Twitter/Google Street View mashup. Stweet is exactly that. It superimposes geolocalized Twitter tweets over the appropriate Google Street View image which changes each time a new tweet comes in. It only works in cities where Street View is currently available, but that number continues to grow everyday. Created by we-love-the.net, Stweet is definitely worth checking out.
