What's your username hygiene look like? Do you use common/similar usernames, or do you mix them up?

Up until pretty recently I never considered that part of my privacy profile, or threat model should include usernames on some accounts. In my quest for online privacy, and to trip up the data miners I've made it a habit to use random usernames across all services.

Do any of you use any tools for this? There are username generators in most password managers. I use this site to generate them usually, usernamegenerato(dot)com.
