AIBU explanation please and thank you

There are common abbreviations that we all use to save time. Some of us have arthritic hands. You will get the odd troll complaining that someone used an abbreviation like NDN rather than typing out "next door neighbour" every time but they just make themselves look foolish.

These are actually very annoying abbreviations and not acronyms Keepitlight
Several people on here find them irritating and prefer to write the actual words.
Despite all that enjoy Gransnet.

Out of the loop here: what does AIBU stand for?

Thank you all!
