I have a blog too, but I wouldn't call it a traditional blog in the sense that it is treated like a diary. It is nowhere close to being a diary of daily events.
And its purpose has changed several times since it was started.
It first started out to record books that I had read and some
activities in my life.
Lately, I've used the blog to record work in the garden and document the growth of trees. I am always going back and updating blog posts to add more information. Between the blog and Google calendar, I have a convenient way to look back over years and remind myself when I planted/pruned/bought a plant, what strain it was, what a Walnut tree looks like when it sprouts, at one year, when the Comfrey flowered, etc.
Each blog post then becomes an independent repository of information on a particular topic for me. It is not like a diary entry that I write one day and then never touch it again.
