I don't really care if the lurkers stay on reddit, but I'd like for the creators to transition here and I'd like for this to be the place where you find the good information.
Rather than berate people who stay, I'm offering carrots / breadcrumbs. In the communities I was active, I'm still monitoring what's being posted. Instead of posting new content or answers I'm composing content (with a paraphrased question where appropriate) here on the fediverse and simply providing a link to my response in the reddit thread.
Will reddit start blocking the fediverse? Maybe. Will my posts be downvoted or banned? Maybe. Do I care? Only in that it reduces the visibility of good content. And maybe that's enough to drive people to look in places other than reddit anyway.
I believe this is a long-view approach to migrating away from reddit, and helping others do the same. Reddit will not collapse overnight (as entertaining as that would be), but rather will be a long, slow tapering as the Next Thing^TM^ takes hold. And I'm hoping that this is that next thing that is less likely susceptible to corruption.
I am honestly not sure if that is the correct approach. This feels like you are trying to force people to migrate over here. Why not just add the link as a supplementary information instead of the only one. If someone actually wants to get off Reddit then it will be helpful but otherwise it won't annoy people for no reason.
I'm only offering a solution or item of interest as a link, no different than linking to the Washington Post or The Verge, or Quora. The interesting thing will be in the link, and Reddit is still just a [back] button away. I suppose I could title the link something like "Experts have solved this problem; you won't believe the answer!" That would be a terrible thing.
I don't see the difference between putting a link here and posting any other internet link.
