Didn't you regret deleting Linkedin? That is specific in my eyes. Different. Professional, even if only slightly. A perfect place for carreer relationship building.
Can you tell the same about Steem? You can consider yourself extremely lucky if yes, that's how I see at least.
I didn't meet anyone important on LinkedIn during my 2 years of using it. I always met the people I needed at conferences, or other meetups.
Understandable, but personally I'd hate cutting even the opportunity.
I guess you're just not the "Linkedin type" of person. Not unlike how the more reputation in Japan you have in an industry, the less name-cards and other gadgets you have, because the less you have to introduce yourself to others.
