Reddit

It's my understanding that the latest numbers just before the API nonsense put the old and unofficial users only at around 5% of the total userbase. While I suspect that they had disproportionate engagement and moderator numbers, I think most of the people who don't care really are in the vast majority who aren't immediately affected by the change.

Just as with any diversity issue (in this case, a diversity of personality types) the majority is going to find the quality of Reddit content will start to slip as the minority leaves. Failing to stand up for the people who are loudly proclaiming they've got a problem is going to affect everyone, even though it's not immediately obvious.

Also, most of the people who really care have already left.
