Blog Names

Ok, everyone knows I'm new at this blogging thing. So I've been perusing other people's blogs just to kind of get an idea. Not famous blogs, simply friends' or friends of friends', and I really enjoy reading them. Except one thing. Why do bloggers make up cutesy little nicknames for their husband/kids/dog? Is it bad blog etiquette if I don't? Will I not be allowed to sit at the cool blog lunch table??? I just don't get it. Is it to respect their privacy? Beacuse I think if you have a blog where you share your families most intimate moments with all of your friends since you were in diapers- you may have a problem with the whole 'respecting privacy' part. I think I may in all seriousness ask this question to my favorite blogger, the Original Dottie Hottie, Miss Kendra of Kendraspondence. Her writing is so rich it's amazing and her posts make me laugh, cry, and learn a lot about myself so much so that sometimes I find myself thinking about them for days. And when she talks about Lovey Loverpants and Tater Tot, I usually find myself laughing so much that I never cringe at their little names. Will get back to you on this...
