A steemit merger with Twitter or one of the other internet megaliths is a great idea and fun to daydream about. After all, they are having a hard time justifying their current market cap after their unrealistic ipo runups and then pull backs. They have a huge amount of users but no clear path to monetization besides advertising or selling out users in other ways which would hurt their platform. The biggest issue I see would be the lopsidedness of the merger. All the Twitter shareholders would basically be converting their dollar investment into crypto and basically becoming a bunch of megawhales. I think the only way to accomplish this is by creating a huge amount of Steem to distribute in the merger. Don't know if that is possible or if there is a mechanism to accomplish this by devaluing the current Steem to make room for the merger share holders. At this point the Twitter side is so big and they would require so much Steem that Steemit whales would become Twitter minnows and the rest of us would be Twitter plankton!
