It's not just you. I hate it. I don't mind the abbreviations if you've used the full name at least once in the post, but I hate it when people just start right out by abbreviating. So if you're reviewing a restaurant and say "Crystal Palace is our favorite" and after that you call it CP, I'm fine with that. But please don't start out with "CP is our favorite."
(I don't object to WDW, though - I figure on here everyone must know that one, and Disney even uses it, so it doesn't irritate me like the others do.)
I also hate all the abbreviations used for family members, like DW, DS, DF, DD, DM, etc. Especially since some of those are used to refer to more than one person. DF= Dear fiance or Dear Father, DS= Dear Son or Dear Sister. I don't want to have to try to figure out who you are talking about. Why can't people just say Wife or Son or whatever they actually mean?! And I really hate the whole Dson/Dwife/Dhusband/Dniece thing. (Fortunately I almost never see it outside of these boards, but there are lots of people on here who do it.) The D serves no purpose whatsoever; please just leave it out. I'm sure they are very dear to you but I really hate that stupid D. Dson isn't a word. It just looks like you made a mistake when typing about your vacuum. Please just use real words and don't make up new ones!
