Opinions, please. Keep entire archive or toss old?

The all point of having archives is precisely to keep a record of the
list, even of "stupid" questions and "wrong" answers... Even mystakes
are good for newbies learn how *not* to do something. And believe me,
i know, i've been a newbie on several technologies since i was doing
Cobol on a  Z80 running CP/M!!!

 So keep it all, unless, of course, there are some privacy issues
around the question...
