There is no particular reason for the switch to medium, the only thing that I found worth switching is the text editor. The text editor from a medium.com is so much more intuitive and cleaner than the one that comes with WordPress, and also now the majority of the programming community that I follow are writing on the medium. So I decided to switch on medium too, and now all of my programming writings will be on the medium.com/@mrFunkyWisdom.
On this WordPress instance, I will probably write more personal and other unrelated topics that I found interesting. nevertheless, I will share all the links to the medium articles and other sources on which I will write.
