If you use one account for everything, you may not be seeing the full breadth of Mastodon. Get an account on an art instance, watch the cool art fly by the local timeline. Get an account on a French instance, bone up on your high school French. Make an instance for your coworkers, talk shop.

I don't wear swim trunks to work, I don't wear a suit to the pub, and I don't wear cargo shorts to my sister's wedding. Apply that to Mastodon and you might find it's quite natural. Decentralize yourself! 😁
