GWoof. I am with you. I loathe acronyms. I use social media all the time and post on StreetLife, and no one uses acronym. To say it is the culture of Gransnet does not mean it cannot change. Why do we have to have DH for instance. What would make us normally write darling husband, darling daughter. I am stil working full time for myself, but can easily find the time to type the actual word.
I do occasionally post on this site, but never use acronyms. No need. It's lazy and it's okay if others want to use them, but really it takes a while to work them out. Each to his own I guess.
