Honestly, the Reddit migration. I switched to Lemmy about 6 months ago. A few of the largest communities at that time were Self Hosting and Privacy related. Those naturally lead me to looking into Linux. From there I started minor self hosting on a Pi. Then, after a rather long walk through the Yongsan Electronics Market in Korea I built my own Homelab, and last week, I moved my primary desktop to Pop_OS. Honestly, It's been a blast. A few learning curves, but the ability to have near complete control over my setup, and the increased self reliance has been delightful.
