It’s true, that’s the advantage of a larger user base. But when I compare my homepage of Reddit after 15 years of refinement to that of my lemmy homepage after 1 year, my lemmy one is way better. Most of those niche communities devolve into memes and nonsense like the same questions being asked over and over and over again after a while. Great for searching, but for actually getting content on a regular basis from, mostly a waste of time.
Yet you already have direct neighbors of Russia like Hungary and Slovakia simping for Putin, so proximity to the threat doesn’t seem to overcome the tendency towards misinformation and manipulation against your own best interests.
