'congratulations, the restaurant you added to Google Maps has had over 100,000 views!'

Things like that help. Also, sometimes when you complain about service, if an owner is reading they might be prompted to take your report more seriously and respond when you have a high level badge, if for no other reason than because your complaint shows up higher in the relevancy sort for a lot longer. I was at a chain deli once and wrote that everything else was great, service, etc., but their new Reuben was a bit soggy. Within hours the local franchisee asked me to email them. I did, and said I don't want a refund or anything, not trying to act like an entitled Yelper, just please train people about the new item, etc. They've had a couple different store managers since then, but I think of it as "my" deli, even though they don't excel in anything, because they've been responsive.
I was having lunch at a very tiny restaurant in an out of the way strip mall much more recently, because I'd had to take an elderly relative to a nearby medical appointment. I had seen it on the map, but it was empty at the tail end of lunch, so I made a point of writing some nice things about the place. Right after I walked out, the guy I'd seen at the cash register (but who disappeared while another person made the food and brought it to me, so I think the owner) came running out and said, 'hey, are you __? I really liked what you said, please try a birria taco before you go.' I was in a hurry to pick up my relative so promised him I'd be back another time to try it, but it was a big reminder how encouraging a good review can be to small owners. I was smiling for a while on what had been a boring, down day.
I'm also a guide because I wish people would do stuff like post pictures of the menus or parking lot information. I figure I should do what I want to see. It saves me a lot of time if I see a place is out of my price range or is hard to find parking near. (Satellite maps help so much with the latter, so I was glad to see through DDG that Apple has those just like Google). A lot of my most popular pictures are just entrances, so people have an idea when they're driving down the street what to look for, what they're next to, etc. I also write about staff friendliness, crowds and excessive noise because I'm an introvert and those things have a huge effect.
I would probably do all of these things for Apple if they come up with something similar. My iPad is only wifi, though, so it won't be as easy until I get something like an actual iPhone.
*I have to admit to getting a little grumbly when I get picture view updates, because I think if they gave me a tenth of a penny for every picture view, heh.
