Ability to save events such as festivals etc, as well.
I frequently miss smaller events that happen once a year because we just get busy. I would love to have an events app that would be similar to this one. Something that would give me a heads up about upcoming events I've added to the app.
Given how well you have executed matchbook, I think you would do this the right way!
I often find and attend a lot of food festivals such as beer festivals, bbq festival etc and would love to bookmark it to remember. Could add it to my calendar, but its only tentative that I may go. Plus i would like to keep these in the same place as restaurants that I want to try, because they are similar.
Also I find a lot of the daily deal sites offer discounts to the big festivals.
