For me, this is a hobby income that often allows me to go out when I otherwise wouldn't work it into my budget. I've been doing it for 2 years and have never seen it be a steady income source. But it is fun and nice to have a little cash here and there.

Unlike other platforms, I've never seen a numerical "shop rating" on ISS. You get points towards the next level, rank wise, and getting badges seems to depend on the editor who grades your shops. Sometimes they count shops towards a specific category and other times, it's just points added to your overall rank.

It's been a while since I've used ISS's website. On there you can see your state's leader board. You only see the top 5 and there are never any announcements about it besides the spot on the website.
