There is no broadcasting involved here. Any information which leaves this site is polled, not pushed - it is up to the recipients which parts they retrieve. The analogy to Radio and TV is flawed.
The analogy isn't perfect, I grant you. But it isn't as flawed as all that. It is equally up to the audience of radio and TV which parts they receive - it's a decision to tune to a particular frequency or visit a particular website. Whether the content is pushed or pulled at that point is a technical distinction. The content is there to be absorbed by anyone and therefore a similar sort of quality control is advisable. Again, IMHO.
As I tried to explain, even poor content is educational in its own way.
I don't disagree (although I think "can be" rather than "is" might be truer). But for those Anonymous browsers who might be new to Perl or even to programming in general, how might they tell the good content from the poor? They might see a post and think, "Yes, I'll do it that way" even though to an experienced user the content might be obviously wrong or even dangerous. In the absence of any of the other methods previously discussed to protect the neophytes the proposed (and current) system will do the job. It might not be the best but it is at least better than what we had previously.
