I hate to sound negative, but right now growth in the fediverse (especially Reddit clones like Kbin and Lemmy) are being driven by people who no longer want to use Reddit. But over the past few weeks, most discussions are still circle-jerking about how bad Reddit is and how glad people are to be on Lemmy. You can only beat a horse for so long before you need other content posted on here to keep most people engaged.
My only issue with Lemmy is that it’s not a true Reddit replacement, especially when places keep defederating from one another. Like I spend far less time here on Beehaw because it’s defederated from some of the major instances - I understand the administrators’ concerns about moderation but over time a lot of the activity will center itself around the most active instances (i.e., users may come from a diversity of instances) but only interact with content on Lemmy.world.
