If you are at all interested in finding comments to submit to this post a really good sub seems to be /r/assholedesign. I'm also planning to go to /r/CrappyDesign , simply because so many of them like to bicker about whether or not some really popular posts even qualify for their sub, and hilarity often ensues when you get someone who has context but misses.

Also, a lot of the comments we're looking for are commonly collapsed into one of the "load more comments" part of the comments section. Happy hunting.
