Buffer offers a free version of its services as well as a very affordable pay subscription. What we like about it... It's easy to install the Chrome search engine app and quickly schedule content on you social media profiles as you find the content. Your posting times can be customized to fit your timezone and times that are optimal for the social channels you are using. Very cool tool!
Want to prototype a storyline for a game? Make a text adventure! An awesome open source tool called twine http://gimcrackd.com/etc/src/ let's you branch out stories quickly and easily. It has a very intuitive interface and is completely free. I think this is great.
UrbanSpoon.com: At first I thought of this as an alternative to Yelp.com, but Urban Spoon is only for restaurants and the reviewers seem be mostly foodies (though I could be wrong). The mobile version isn't as user-friendly as Yelp's, but quite a few Washingtonians swear by it just the same.
