I never used the social media sharing option here on Musing, just like I never did on my posts on Steemit. I have been writing online and I never shared my posts as well. I just want my write ups separate from my social media life. Besides, I rarely open my Facebook account.
The sharing option whether it's underutilized, I agree. I don't even think there's 10% of Musers sharing their Musing posts in social media.
I am using Musing since 2018.11.27 (27 days), but I didn't/never used the sharing option so far, and I am not planning to use it at all.
Probably yes, the sharing option is the most underutilized option on Musing.
