Hi, it might be against what most people feel and think right now but I feel that it needs to be said.
I come from rational place even though I currently hate reddit and removed it completely from my devices, but I'm not going to delete my posts or nuke my comments.
Like it or not Reddit is still a huge database for a lot of solutions and great posts and discussions about opinions, reviews, how-to and many many more.
Lemmy will take time to keep the pace and be filled with these types of content. And it might might take years to get to it (I really hope it will).
Deleting and nuking posts and comments are only distroy what we and the entire reddit community built over the years and it will be a huge loss for all of us.
If you ask me, the best way to say 'fuck you' to reddit, is keep all the old Content there, try to migrate as much as we can here and from now on build this content here.
When/if Lemmy be mature enough we can go back and fuck everything up on reddit.
This is my 2 cents.
Maybe a happy medium is to take you best/most popular posts and repost it in here under a similar community, then edit your Reddit post to point to Lemmy for additional info...
This is a much better answer.
Reddit's only real value is the contribution of users. Reddit got so big because it had so many users posting their information. It will continue to be big so long as it's the place where you can find answers to nearly anything.
Move the content, and you'll move the value. That's the only way most people will ever change what site they browse while pooping
