I'm not being sarcastic. Sometimes writing in a way that's easy for other people to understand is just hard. Speaking for myself, normally when my own comments aren't clear it's because I've spent as much time as I'm willing to spend on writing a comment trying to come up with clearer ways to convey my idea, not because it feels gross or because I'm not trying. (For example, I rewrote that last sentence at least 4 times and it's still pretty clunky.) This seems to come as second nature to some people, the rest of us have to struggle a bit.

None of this is intended to detract from your point. Clearer writing is better.
