Five posts a day isn’t bad as you put it. You’ve been for years overstimulated by Reddit’s abundant content. Many of us have been contributing to lemmy perfectly fine; we see reccurent usernames and profile pictures, we grow compassionate and sincere with each others thanks to this familiarity.
Not everything should keep on mindlessly growing. Not growing fast enough isn’t a problem, yet our modern, capitalist lifestyles make it seem so. That said, I am not against lemmy’s ongoing growth per se.
