A WordPress plugin that helps people share your content via powerful quotes. Provides an interface for sharing selected text directly to twitter along with a link to the original content, and credit to the author. Also provides an interface on blockquote elements for sharing those quotes directly.
You can either download and install the zip manually, or find the plugin on WordPress.org

If you want to see this plugin in action without installing it yourself, check out this page on my blog: http://josiahsprague.com/destination-isnt-point/
Look for the Twitter bird on the blockquotes near the bottom, and try selecting some text with a mouse and see what happens.
In no particular order
[ ] Add detection for twitter:// protocol to open links in app if installed - it looks like this might not be possible, if anyone has an idea for how to make this work, let me know. [ ] Don't add quotable link to paragraph elements that are citations [ ] Add option to share on reddit
