Mav's idea is to call the discussion "sorting" rather than filtering. Filtering has a negative sorta connotation - and theres a reason for it, as has been stated.
And sorting is sorta different, wouldnt we say? There are sorting features in WP now -- recent changes, news articles, - any search you do is a sorting, of sorts.
So as a separate discussion, we can discuss sorting, -- but with the clear understanding that *"sorting" means "sorting articles" - *not "sorting people" for the appropriate article for them.

Wikipedia is available to everyone. So far, the threat is completely hypothetical: no school has blocked Wikipedia. Maybe, before rushing to action, we should give schools more credit. If indeed at some point some school blocks Wikipedia, we can, after reaping the benefits of a nice New York Times article and ACLU lawsuit, set up your edupedia in a matter of weeks - the sifter code is already in place.
