RE: The Digital Monopolies of Content and Interaction
There is one major factor in the history which you have documented in your post. Decentralization. Perhaps we should be looking less to "take over" the other social media platforms but, instead, absorb them.
Ways could be developed to link all our social media accounts through the steem account and everything we post to the other platforms could become a part of the blockchain with links to take you into the other platforms.
Just thoughts off the top of my head, yet we should try to be the Everything Social Media and competing against no one; instead absorbing all other platforms' content into the blockchain... or the content generated by steem users at any rate.
There is no more "winning the market" in the present decentralized social media landscape. Smart apps may be able to absorb it in an open source kind of way.
That's a great idea :) It would make it a one stop central platform to go everywhere ;)
Before my extended absence from FB, toward the end of my stay all my posts would be links to steem postings. We could offer that for a start. Pethaps some check boxes on the post submission area where you could choose to mirror a post. If a photo perhaps Instagram, regular post FB, etc..
Thinking further this could be handled as a browser addon or a javascript app. No need to think on the major fork level.
