Thousands of my tech posts are searchable at https://gadgeteer.co.za/blog
I blog daily about tech news, green tech, and open source software that is probably of interest to most people, and it is easy to search on my blog for any topics covered before. I also have a focus on tech news relating to South Africa specifically, but there are hashtags as well when the news relates to any other specific country or broad category of technology.
It's my hobby so there is no paid advertising or information sharing done by me, and my only criteria for selecting what I blog about is the news must catch my eye when I'm scanning feeds daily.
