Really? I can imagine a use for "Patronising member" and "Pompous member" level tags...

I like the idea of something user-settable after X posts, that would probably become fun and useless in the way GA originally proposed.

But I also like the idea of a descriptive field, "hardware developer", "alternative OS user", but can imagine that a large proportion of users would feel they bridge too many categories (and that's what sigs get used for anyway).

I'm not so keen on the OS version hierarchy, just because it will confuse some poor newbies when trying to dismabiguate their platform from the user level of their information sources...

The "no thanks"/"thumbs down" has an immediate appeal, but I think reasonable objections have already been advanced.
