Allow me to dislike a place.
I want to use Matchbook to also remind me of places I don't want to try. So add another option for a place that I've tried. Either I've tried it, loved it, or disliked it. Then, don't show the places I dislike on the map view but leave them as a bookmark so I don't lose the data. Furthermore, add a percentage of people who loved the restaurant (of all the people who tried it) so that I can see what other matchbook users think. Thank you!
I choose to remember good restaurants, not bad ones. When I eat somewhere less than great, I am not going to bother remembering the name. I would like to write down the name so if someone suggests it, I can look back and review my sub-par opinion of the establishment. It's the same reason I rate movies on IMDB, eventually I forget how I felt.
