The Huffington Post article (huffingtonpost.com) about iOS apps that upload contacts in the clear & store them on their servers is pretty concerning. Where I grew up, this would have been considered totally inappropriate & scandalous. I'd be outraged if I'd had this done to me. As it is, I'm glad that most of the people I help with their stuff aren't big into the social networking stuff, so should be OK.
Not OK, & never would have dreamed that anybody else would have thought it would be!
Do we know why the reference article (& its embedded references) cite iOS, & all call out iPhone specifically, but don't mention iPad? That certainly has a whole set of contacts information.
I have Netscape 7.1 myself ... No real complaints, and it sure seems to me (from the brief experiences I've had with it) that version 8.0 and up aren't worth the upgrade because of the little nuisances.
