I have been a lurker of the various Sanderson-themed subreddits. Unfortunately for me and my fellow introverts, there isn't much here to lurk at (yet!). I thought maybe we could get things started by discussing how we all got into the Cosmere. I'll go first!
In November of last year, a friend of mine recommended I read Mistborn. I had just barely started reading again after a long break and was in need of a new series. I was about to go on a long drive, so I borrowed the audiobook from the library so I had something to listen to. I didn't realize what I was getting myself into. In the last six months, I have read every single Cosmere book I could get my hands on, and have absolutely loved each one. I finished it all off with Tress last month. My only regret is not getting into this sooner so I could have been a part of the Secret Project Kickstarter.
I saw a recommendation in a thread on /r/books over at reddit actually! I started reading around the time of Words of Radiance, and went through things pretty slowly in a relatively unintuitive order:
Way of Kings
Words of Radiance
The Final Empire
Warbreaker
Oathbringer
The rest of Mistborn Era 1
Elantris
Rhythm of War
Mistborn Era 2 (Up to BoM)
Arcanum Unbounded
The Lost Metal (Went to Dragonsteel 2022 for this!)
Since I've caught up I've gotten probably a half dozen people to start reading, and have been carefully curating their reading order to avoid the nonsense I went through.
