I've been wanting to know this for a long time. On more than one occasion, I've been seriously surprised when some diarist or commentator reveals their age, either directly or indirectly.
I also get a kick out of "Kos Kidz" which is what some of the wingnuts call us. A while ago there was a poll about level of education and I was dumbfounded to find that something like 20-25% of Kossacks have PhD's, and vast majority have college degrees (at least at the time I checked the diary). But that's crazy! I certainly didn't expect it.
So, "Kidz" is likely not accurate.
But... You have to admit, as belittling nicknames go, it's not half bad. Certainly better than "Late German Fascists" or "Assrocket."
Anyway.... put down your age in the poll, and recommend this diary so more people see it.
Don't worry, it's all anonymous. :)
BTW, I'm 28.
