With reddit having way more people and being only a casual browser, I would never make it early enough to a post to contribute in a meaningful way. Whatever I would have said would be commented dozens of times before I got to the thread. At best my comment wasn’t made yet, but I’d be sure someone with more knowledge on the subject would’ve contributed in greater depth soon.
Here I see plenty of posts hours old with no comments. There’s a greater chance whatever I might say won’t get buried or overshadowed.
