I'm fine with there not being an exact replacement for Reddit.
"The alternatives will never be as big as Reddit" As if reddit having that many users is a good thing, the majority probably never comment, just scroll through on mobile looking at gifs, pics, short videos. And if they do comment it's the most cringe inducing, asinine attempt at being funny. Oh the 7 billionth reference to The Office. A Simpsons reference? Wow! A pun? How funny? Reddit's huge size is a negative, not a positive.
"But the post with useful information to answer your questions" -
Yeah, there are useful comments or threads, but in all honesty a lot of useful advice on Reddit only seems useful because of how oddly specific it is.
Post showing car veering off the highway and rolling over into the grass. And the top comment will be like, "Little known fact, but I actually used to work as a highway planner for my state and all highways in the US have little markers with unique numbers on them every 50 feet. The markers have a little dot that align with the position of the sun or brightest star. If you go to the marker, turn on the spot 3 times while staring at the sun, then divide by the square root of the highway number you are on, you can get the exact coordinates of your location"
