Meh, the "damn nokia for keeping me waiting"-ers can go hump a brick wall. In a few days the devices will start coming in and over-excited teenagers can finally use daddy's cash and get their toy.
Also, hate mail is pretty easy to identify and swiftly delete
Also, those nokia people that i know of are pretty easy to spot anyway (especially peter), so i don't think they're hiding very well. Newbs would probably find them harder (which is the point of this discussion), but don't forget the troll-vision annoying people have, allowing them to easily find targets
Of course, everything would be optional. I'd just like to see a spot (besides the signature) where people with some relevant quality can show it, and dev's can show what they made (a tag like "Dev/contributor of [insert app here")
