I’m a first-timer, too, but have been doing it for a couple of years. I have an overall theme, which is ways to make our world more kind, just, and loving, one small act at a time. But I’m not serious all the time. I add humorous posts, including cartoons and word-origins that have interesting, sometimes silly, origins. I think variety is important. But I think there are too many blogs that say, “Look at me and my family!” so I generally avoid posting things about either me or my family (once in a great while). And keep your blogs short, because people are lazy readers.Good luck! By the way, don’t expect a lot of comments coming back to you.
