I don't focus on the bad, but it's much easier to quantify the bad. We also, frankly, tend to cut our friends a lot of slack on their flaws and inflate their good qualities, while zeroing in on petty bullshit from randos and people we don't particularly care for. It's human nature, but it makes me reluctant to either call people out by name unless they've become complete atrocities, or give someone a public compliment unless they've done something amazing (I give private compliments pretty frequently, and it's the kind of feedback I put more stock in and prefer to receive myself).
With all that said, I did have an experience recently as a Guest that I really liked. I was actually invited to watch ongoing RP, and @tel'd to the grid by staff so I can get a sense of what an actual scene was like. I wish more games would do this, as the way the players and ST interacted gave me a much better idea of how the trains actually ran at this place. There are obvious pitfalls in doing this (namely, a lot of People on the Internet can't master basic courtesy and will be disruptive), but it was the first time I thought, 'Huh, this is a decent idea and there are ways it can probably work.'
