I... mis-parsed the reply as saying that bloom filters haven't been part of a curriculum from which to remove it, and took it as a dig at the lack in CS curricula (which sentiment I would empathize with).

When Google first brought it to light I know most of the people I had access to had never encountered Bloom Filters in their college carreers. I can think of a handful of other things we 'should have learned' in school that just never came up (and I'm not even talking about practical skills, just theory).

Apologies for the mixup. Interesting to see the mix of up- and down-votes I got from this one. I wonder if some people made the same mistake I did...
