Well... I understand that having high expectations of others is unreasonable. Still, I think that if someone posts an entry, it's asking people to spend their time and energy correcting this entry, and effort must be appreciated.
I don't hold grudges, but if I corrected someone's notebook and they didn't react to it, then I assume they didn't look at it/it didn't help them and then I avoid correcting their entries since they can't draw anything from it. Better to correct the entries of someone who can learn from your corrections, don't you think.
