User blog comment:Brandon Rhea/Wiki domains will be changing from wikia.com to fandom.com in early 2019/@comment-35245651-20180820110824/@comment-25464118-20180821142151

"At the end of the day, FANDOM holds all of its important communities hostage and they know it. Any community outraged at inevitable changes that tries to leave nowadays is doomed to fail."

Not necessarily.

The Yu-Gi-Oh! wiki forked earlier this year and we've seen nothing but success since then.

Since the fork in February we've added:
 * 799 new articles
 * 1,058 new images

This month alone we have attracted more than 85,000 unique visitors to the site. We're currently sitting at 3.8 million page views since Google Analytics was added to the site in March. This does not include views by wiki administrators or bureaucrats.

Regardless of what the Wikia version's numbers look like, this is huge. You can't expect to fork and immediately take over your Wikia version in a month. Your readership will follow the best source of information and that's clearly what is happening now.

So no, forking doesn't mean you're dooming your community to fail.
