Before the whole Reddit migration I was passively aware of the Fediverse, I thought I somewhat grasped the concept, and had created a Mastodon account, but never really used it.
But once the migration started, I decided to try out Kbin, and really liked it, and even started to use Mastodon more often.
Zero! Zero familiarity! When I heard about Lemmy during the Great Reddit Migration of 2023 I was like “What a stupid name. I should code my own Reddit and get rich. The time is now!”. But then I realized I don’t want to code Reddit after writing code for 6-10 hours a day at work, and I checked Lemmy out. Then I learned about the Fediverse. Then I was highly impressed and gave many oohs and aaahs. Now I’m off Reddit completely (except for CenturyClub from my desktop like twice a week for 10 minutes) and this is my home. Yay!
