I'm also switching to Kbin (subscribed to lemmy instances too) where I spend most of my time now. I miss my thematic subreddits, but experience says it is a matter of time until I build a good network here. Mastodon took me 6 months to be able to replace Twitter almost completely (there are a few individuals I still have to find somewhere else).
I blocked reddit from my DNSs and I only enter via Infinity mobile app every now and then to vote on the polls to "keep the blackout" or "only allow John Oliver shenanigans".
