STEEM has a pretty massive First-Mover-Advantage though admittedly Steemit Inc and some of the top Witnesses have shat the bed so it may already be squandered.
I wrote some months back about trying to expand SSG to a new platform but I think until there is a new market leader in this space it won't happen smoothly and it would be unwise to try until we have a critical mass.
I have also mentioned the idea of multi platform to others but i does not get much attention, like you said, theres nothing to fill the gap. You any good at building websites? We could build our own forum and use a erc20 token pegged to STEEM/EOS/BTC. Building a forum is easy, but adding in and funding a rewards system is over my head, lol.
I use the tag when I post on whales, weku (if its ever actually up) and leave tags in trybe or narrative posts. We will see, I am guessing I am mostly just writing for myself, and no profit will ever come since I started buying at $4
