I think some of them are okay like posts totals. Maybe not like 1876 or 3452. But maybe 100, 1000, 5000, 10000 since those seem to be major landmarks for people. Also getting a new job or being accepted into a college or a university or getting married or having a baby - I find those completely fine. Ones that I wouldnt find fine are: "Hey, I got out of another speeding ticket!", "I passed my Math test!", "I can play the piano five times faster than you!", "I didn't use to like mushrooms but now I do!", "I cleaned my room today!", "I acutally made something that tasted half-way decent!"..... you get the picture.
