Every now and then, you're alone going through a stranger's Flickr stream, and you see something so laughable, so obnoxious, that you feel the urge to start a new meme but can't be troubled with the effort of registering a domain name and trying to get all your friends on board. Perhaps you're reading a blog and feel the need to comment, but don't want to expose your brilliance to the entire reading world. Or perhaps it's just late and the signup process for comments is ludicrously complicated.

Zingr allows you to spread your insights - and share those links - with your Facebook fandom, all with the click of a button. It's a Firefox add-on, and it's magical.
