"Same posts each time I open my app, always the same boring topics about bugs and how people feel, this is getting old fast."

So you decided to do the same thing yourself?

I am not sure how well Lemmy UI works (I have heard that sorting posts is kinda broken) since I am on kbin and things look pretty lively here.. but its not fair to compare the depth of content communities that are just months or weeks old to Reddit where we have all spent years generating content. Organic content generation takes time, so be patient and engage and produce the kind of content you want to see here.
