This website is hooked up to this Google Spreadsheet, which I've shared, so click and add your favorite hack spots!
When I'm visiting a new city I'd like to know which coffee shops have the best vibes, great coffee and are good for hunkering down and having a good hack. Yelp will tell you where the Starbucks is and Foursquare will tell you where your friend's have been - but did they like it and was it a grab in go place or a hack place? Plus, what about the people I don't follow on Foursquare or who can't check-in when in other countries?
Besides being a list I've wanted to have, it's a fantastic (or I think so) way of using sheetsee.js, which is a little JavaScript library I've been working on. Sheetsee.js helps you hook a Google Spreadsheet (awesome for data and collaboration!) to a website to make data more visual (maps, tables, charts).
