coming back to the post that started this thread...
a) Initially USJ was associated with terrible jams but I think it has improved a lot and I would say it is bearable
b) Yes, some people think we are an above average income community but I disagree if anyone thinks we are rich...there are higher income communities like Bangsar, Damansara (Heights, Utama, etc), TTDI, Tropicana, Gasing to name a few
c) Crime is everywhere, including unlikely places like Taiping (there was a murder a few years back). In USJ/SJ, I dare say it may be correlated to the number of immigrant workers and maids - so be extra careful of possible break-ins if there is a house renovation nearby. As for maids associated with crime-contacts, I think it had lessened because of the recent clamp-down on availability of maids from one of our neighbouring country
