I thought I'd create an open thread Scott and I's project, http://pinballmap.com. In this thread, we'll post notable site updates. And you can use it to give feedback or make suggestions!
Pinball Map is a website, and it has native Android and iOS apps. It tracks publicly playable pinball machines. The data is updated by users. Scott and I started it in 2008, as a Portland, Oregon map. Then people asked us to make maps for their cities, so we did. At the moment there are 65 maps on the site. This blog post has more details on the site's history (focusing on the technology we've used).
The site is free and ad-free. We consider the data to be the users' data, given that they update it while we just supply an interface for it. The site is also basically free advertising for businesses and operators.
We add new maps when people ask. Our goal is for each map to be locally supported, though we have little control over this. But we require that each map be administered by a local person. The admins have more access to the data, and they are crucial to a region's success (a successful region is one that is updated frequently and is valuable to the people who live in or visit the area).
If you want to help out as an admin, you can! Just ask.
The site code is open source. Anyone can contribute updates. This is just a side project for us, but we care about it and are regularly updating it. As you can see, since we started tracking on github we've committed 1,708 updates. If you have a feature suggestion or found a bug, you can open an Issue here (or just reply to this thread). That Issue list also gives you an idea of what we're working on - such as a "find closest locations" button for the website... which basically means the most valuable feature of the mobile apps will soon be on the website, too!
We have an API. You can do all kinds of things we the with API, such as listing machines on your website using the data from our site.
We have a blog where we post news and crap. We don't have a facebook presence. We have a twitter that dumps out location updates for every region. It's likely TMI for most people, but it's a fun way to track updates. There are also many Twitter accounts for individual regions, many started by the admins.
A good way to contact us is through the form on the Portland "About" page.
We use the IFPA's API to display nearby Events for each region.
The website is mobile-optimized, so it works well even if you're not using a native app.
We love feedback! And we're happy when people find the site useful. We think it's especially useful for newcomers who don't know where to play pinball. We especially value people who put their time in and update the data (because updating maps is fun!).
