It is difficult for me to describe just how angry it makes me that reddit doesn't provide a way for users to even do basic things like "see all of my own comments" or "see all of the posts made to the subreddit I moderate". They keep nerfing the search APIs and claim it is so they could make the indexes more efficient, but while that might make sense for a full-text search interface, that is entirely unreasonable for basic functionality like "I'm scrolling back through time on my own user page" (where the efficient index is pretty obvious). Both of "see all of the content I posted" and "see all of the content I'm supposedly responsible for" seems like it should be basic, if not required, functionality for any website.
