Don't think I'll go as far as deleting my account as it still holds some sentimental value to it (things nearly 15 years old at this point) but as for browsing / general usage, yes, I've fully switched to Lemmy as my daily site. While there are a few niche subreddits I'll probably still periodically check in on the sites been going downhill for years now, and the most recent AMA / API tomfuckery made me jump ship to greener pastures.
