Scare Your Visitors with this JavaScript Gravatar Plugin

Here’s a use case. An unregistered visitor visits your blog, and decides that your content is so good that it merits a comment! Congratulations, you’ve fooled them! Now you can twply their account details for $1200 on Sitepoint! Just kidding. But generally, when you visit a blog’s commenting section (such as the Tournology Blog shown above), you’ll see a simple form to authenticate you’re not a spammer, generally including (among other things) an e-mail address field.

Well, since they’re typing their e-mail address, wouldn’t it be cool if we could show them their gravatar right there, inline with the blog comment form? Well, that’s now possible with my new JavaScript Gravatar Plugin! It doesn’t have any server side language dependencies.

Hell, gravatar.com could even use this to improve the user experience of registering your e-mail account. Right now it does a full page refresh and doesn’t even show you a preview!
