Maybe it's time to expand the Top20 to Top100 witnesses, so we don't have to worry about taking over and removing the dependencies of strong blockchain to few witnesses.

The SteemIT.com developers are paid employees of Steem Inc. Justin Sun is not stupid to disrupt the current operations. Like you said, the roadmap is not clear at this time. But history speaks for itself from the many company merges, one dissolves slowly and that’s what we need to be prepared.

Steem Inc provided back-end for the developers, including api.steemit.com, steem.com website, etc.

We need to show the steem community the alternative back-end servers, front-end websites, open-source codes available to them. This will help calm this issue.
