I have been on youtube over a decade and though there are changes I don't like I understand it's their site so I abide the rules... I'm gonna to tell my experience (which was on fb) I was not talking about crypto for me this was always a BLOG and a new network to share my work. I've never cashed out anything.

I will not be dishonest... I am verging on my third year on steemit... I post scarcely but steadily, but here I am, my blogs on steemit rank well on google, so I know many of my friends actually found my blog here just looking for me. I have made an effort at least that they stand for quality, some even are not replicated in my own blog and are posted here before (or ever) but I do not do steemit shout outs on youtube, facebook or ig. I was asked recently very kindly by the ocd team to do it, but I'm trying to break a rather stalled algorithm. My experience was that candidly I promoted (as logical ) my blogs and dlives (back then when dlive was a steemit dapp) on facebook, I also got posts deleted and a warning and I was shadowbanned losing all my reach for a long time, my account NEVER recovered the reach it had before. So youtube which is officially linked to the label is something that I take care a lot of care, with everchanging rules I finally understood I do not own their places or what they like. Twitter seems pretty neutral so sometimes I do a little shoutout or indirectly by following and supporting many of my steemian friends that are there. But let´s face after my experience I even fear that might change. For me every network (including this one) is a window to expose my work, so I abide the rules but we also must be aware of what they allow and not.
Just my two cents.
So my way to promote this community is a) post quality content that ranks well b) connect and engage with fellow community friends (here and out of here). Because for me at the end it's a group of people I met on this platform and that has trascended. Approaching my 3rd steemversary
