Cortex for Chrome is the fastest, sexiest social media sharing extension yet

Cortex is a must-have Chrome extension for anyone who shares links via social media. Instead of adding a button or right-click-activated contextual menu to your browser, Cortex pops up an innovative sharing circle when you hold down your mouse button. The circle looks cool, sure, but it's also a quick way to share stuff on Twitter, Facebook, Tumblr and Instapaper without even clicking. Just drag to the part of the circle you want to use and let go. You can even set up Cortex to share with specific friends on Facebook.
Once you choose the network where you want to share, you'll see a prompt to add a note and you can then hit return to send it. That's it. It's that easy. Cortex has some weaknesses, though, depending on your sharing habits. Social media pros who need to post to a dozen networks at once probably won't find much use for it, but the average user who has accounts on the four Cortex-compatible networks (and doesn't cross-post often) will love it.

A couple of tips: holding down your mouse over an image will let you share that image instead of a link to the whole page. Also, if you share something by mistake, or accidentally pick the wrong network, you can cancel by hitting escape.

Check out the demo video of Cortex below to have your mind blown by how quick and slick sharing on the web can be.
