I'm not a huge techy either. I'm more of a jack of all trades. My knowledge is that the tech behind STEEM is like a prototype EOS. If a person wants to run STEEM on EOS it shouldn't be that hard. GOLOS is a Russian fork of STEEM and YOYOW is build using the same tech with a focus on China.
Getting people to use the EOS DAPP instead of STEEM will be the most difficult part. With SMTs coming and witnesses already being a big deal on STEEM and whales owning a lots of valuable tokens will make migration little tougher. Somebody could build a better version of STEEM on EOS. That's s better route to take instead of migrating.
On the other hand Bitshares may end up moving to EOS. I've heard several people discussing the idea very favorably.
Interesting! On the topic of alternative Steemit's or forks of Steemit - what do you think of sites like busy.org? I don't really understand the purpose. Is it just a more user friendly version of Steemit using it's blockchain?
People just like different flavors. There is https://dmania.lol and https://beta.chainbb.com/ which are using the exact same STEEM blockchain.
There is no one size fits all solution and I personally consider them to be welcome additions. SMTs would further increase this diversity IMO.
