I read that blogs started in 1999. With a clever bit of wordplay someone took the word weblog i.e. a log on the web, and made it “we blog”.
I have been posting regularly on LinkedIn for five years and have had my own website since 2020. So I know I’m a bit late to the party. But having a blog definitely gives a bit more space to elaborate on the one or two topics where I feel I have something to say.
