Graham Spencer had an idea — He asked indie app developers to say "hi!" to him on Twitter. Roughly 200 did. He used that data to create a Twitter list, but he also compiled it into a table that includes where the developer is located, what apps they make, and their Twitter handle. It's an amazing piece of work. MacStories:
These are developers that have made some of our favorite apps, make valuable contributions that help the community as a whole, or are themselves influential in the community. Just like the other list, this is not a conclusive list. We have had to use some editorial judgment to keep it to a manageable length – many others certainly deserve to make it onto this list.
It's also an amazing group of people. If you're interested in the indie dev and the indie dev community, check it out.
