When I heard about musing for the first time, I was kinda confused. It seems like having some sort of connecting with music. lol...
What I know the meaning of "Musing", I'm surprised. And it is really interesting.
Musing means think about something carefully and for a long time. It also means meditation or comment thoughtfully.
I think that Musing is a catchy and awesome name for a question and answer platform. Hope this answers your question!
