Yeah fair enough, I did say it wasn't designed for that though, I think I meant more like '[and] it doesn't drive engagement [in what the core product/use-case is] [so that's not a cause for a push to make it work well, history well discoverable etc., either]'. But basically I agree, my intended main point was it's not for that, you're not supposed to be spending much time reading old discussions.

(And I think the engagement cynicism might be at least a bit correct/warranted for Reddit.)
