Yeah, but for now i recommend X, firstly because steemians are able to keep track of this post, secondly it is a space for web3 enthusiasts, though most social media reach are also based on the keyword proxy, here our post is not limited to the number of followers and X is trending now.

If you really want to promote on other social media, i think just sharing of link is not enough, facebook, youtube, instagram has no one interested in clicking links, but content creators who create funny stuff, motivational speakers, pastor etc, everyone wants to share something that attracts and beautifies or watch one.
