An analogy is in order. Praise is like a field of green grass and flowers. It's pretty, but boring. Occasionally you get something cool like a bunny or deer running through to spark momentary interest, but 90% of the time it's a snore.
Complaints is a rough and tumble bar where anything goes. People tell funny stories, get drunk and to stupid things, and occasionally break a chair over someone's head. It's more fun and interesting, and I get more laughs out of it.
