Today, opening stackoverflow i have read 3 or 4 times the tag QT. For sure is something totally random but this made me think about a friend that this morning talked about how .net is gettin in shadow and c++ is coming back and made me think also about a kind of infovis on stackoverflow data.
Has any infovis about tag trend (for example) ever been tried on stackoverflow?
Speaking about tag trend during the last 3 years for example, have you ever thought about some statistical reduction of data (because I assume that data are too many per hours for making a complete analysis)?
Could you be interested in some kind of project on stackoverflow infovis?
EDIT: thanks to comment i have just found http://data.stackexchange.com/ .. nice place where to start for some infovis! but.. are there some already done good infovis project?
