soliek,
It seems to me that the two “sides” in this security debate are converging towards agreement.
I mostly agree with your blame-the-one-who-foolishly-gives-out-too-much-personal-information-and-let’s-get-on-with-it argument, but there are some cases where posters, especially younger ones, may not realize they are giving out enough information to uniquely identify themselves. This is where I see a place for the security discussion. Not witch hunts, not Joseph-hunting (he’s certainly not the only sock puppet maker here!), but just gentle words of caution. Like suggesting one write, “I was at my cousin’s wedding recently…” rather than, “I was at my older cousin’s wedding in St. Louis last night…”
