Personally, there are some smaller communities that exist on Reddit that just don’t exist on Lemmy, or have inactive communities. The other option for some of those communities is Twitter, so I’d much rather just check Reddit. I also don’t expect my local towns subreddit to move to Lemmy from Reddit. I think it’s less about returning to Reddit and more so wanting to participate in small communities that exist in Reddit.
Funnily enough, when I go to a restaurant and they have receipts with QR codes (I think it’s Clover), it just doesn’t work in Firefox.
