I'm not really involved or in a position to act on something like this; I'm just a user passing by. Bearing that in mind, I have a thought about this topic that your question teased out.

Reddit has become increasingly bad over the last several years with low quality karma farming, predictable shitty overused in-jokes, Facebook style content, and spam/scam bots. The recent decisions by reddit made me realize it was time to go, but that was just the straw that broke the camel's back. All of the other terribleness that reddit had to offer were the most significant causes for me. Yes, there was absolutely some amazing, informative, high quality original and thoughtful content, and I'll definitely miss that. But here there is the opportunity to make something new. Something better.

Reddit has some strong positives that can be inspirational in the fediverse, but we (in my opinion) shouldn't be trying to clone reddit here. Therefore, I don't think we should be setting up bots to crosspost everything here and eventually make this Reddit 2. Of course, others have their opinions which are entirely valid. Just adding some thoughts to this matter.
