I fully agree with your view. About diary deletion, I think once commented, a diary is a collective thing, so deletion shouldn't be allowed after comments have been posted. However, if a diarist wishes to delete a diary, it should be possible (by administrators) after consultation of the posters.
The problem with restricting own-diary editing by default is that it would require admin intervention even for trivial reformatting and typo correction.
For that reason I advocate keeping things open by default until first offence or threat of offence and then people can be deprived of self-editing abilities. Which is basically what has happened over the past two weeks. We have met the enemy, and he is us — Pogo
AFAIU, at present that becomes a delete ... indeed, it may well be that that is what "delete" does (I certainly have not looked at the code to know what the delete button actually does in process terms) ... it would have to be re-programmed to become dummy text, because the system is not set up to cope with posts with zero content, even if they do have comments attached.
