We are thinking of adding a rating system so that users can rate the places they visit. Think journaling meets Yelp / Foursquare.

Obviously no rating system is going to be perfect. Yelp uses the five star system. Foursquare uses a 10 point scale. We are leaning toward letter grades.

Why I like letter grades:

1) Precision: A, A-, A-/B+, B+ 2) Less ambiguous: I have a strong understanding of what a B vs a B+ means...not so much with 6.5 vs 7 or 3.5 stars vs 4. Perhaps that is just me. 3) Widely adopted: http://en.wikipedia.org/wiki/Grading_systems_by_country

However, we're not 100% sold, and wanted to ask the HN community.

* What rating system do you prefer and why? *
