Thank you, genuinely. I really would appreciate posts in Meta letting us know when we’ve made an integrity mistake.
I will let you know that with the mass-import of legacy posts, we did not re-read each one (on the order of 10,000) to determine this, and at some point that problem needs to be solved, to maintain integrity of the categories.
I believe Oliver used an algorithm that put posts above a certain karma threshold in frontpage, and I think it will be required that he/Ray/I fix this if the categories become easier to search (but that at present the key place for enforcing this norm is new discussion). Probably the solution is to put all posts in personal and give mods a norm of moving frontpage-appropriate legacy content back to frontpage as-and-when they read it (which should happen significantly more as the site gets built up).
Actually that just seems good to me right now. If it’s not too much time cost I’ll ask Oli/Ray to do it now, and otherwise when they get around to improving search-by-category.
