if I randomly followed you it's for any of these 3 reasons
 1. I love your books or wanna check them out 
 2. I like your reading list
 3. YOU ARE A BLINK I FOLLOW EVERY BLINK I COME ACROSS- had to actually unfollow a lot of people because apparently there's a 1000 following cap so when I tried to follow actual writers and people with great reading lists I couldn't so sorry but I had to unfollow a bunch of people and stop
