Well this something exciting I would say
While we do have a name for most of the users who uses different dapps like
Steemit users are often known as Steemians
Dtube users are known as Dtubers
Steemhunt users are known as Hunters
Dlike users are also called Dlikers
While according to the curation guidelines of Musing the users of Musing were called upon as Musers. So we the users of Musing are officially known as Musers.

I think "Musers" would be the best title. Literally "people who muse". It fits pretty well with people searching for answers!
"Musos" and "Muses" are too musical / artistic for my liking.
Definitely musingers in my opinion. At least this is how sounds the best for me.
