In all honesty, I don’t make use of federation (and I’m aware of the irony in this specific case). I like this little corner of the internet. While .world would provide wider exposure, I’m about 25 years past going for the widest possible audience when it comes to things other than news.
In all honesty, I don’t go there, as they’re an extension of the subreddit. Pointing out the failures in, say, Discovery makes me a bigot.
