I have one, or more, but for [reasons] they are currently offline.
I keep a hand-written almost-daily diary which I write each morning whilst the porridge is cooking. It's remarkably repetitititive and I doubt that it will do much to enlighten historians of the future. It might upset some members of my family if they ever get to read it after I've shuffled off this mortal coil. I started writing it in October 2020, partly because I was finding lockdown increasingly boring and I thought I would record how dull it was, and partly because I wanted to reacquaint myself with writing with a decent fountain pen using good ink on good-quality paper (tips hat to Woofage...).
Every so often I still write a Ride Report on here. Again, lots of repetitive stuff, but there are some lurking around which have given me an entertaining hour or so as I read through the stuff from some of our tours.
