Snap to it!
On a limited number of blogs, about 10% we’re testing out a plugin that allows you to have Snap Preview Anywhere (SPA for short) enabled on your blog. SPA is a little widget that shows people a preview of the page on the other end of a link when they hover over it for a few seconds.
I tried it out on my personal blog and really liked it, we’ve had a fair number of requests for it, and we think the Snap guys are fun to work with so we thought we’d give it a go here on WP.com.
If you’re a lucky member of the beta group be sure to send in your feedback about what you think about it to help shape how/if we roll this out for everyone.
Finally if for whatever reason you dislike it, you can disable it for your blog under Presentation > Extras. If you never want to see it again anywhere in the world on any site click on the question mark in the preview box and they have a link that sets a cookie so it won’t show up anymore.
Update: If Snap isn’t on your blog or you only saw it briefly, don’t worry. If you like it just leave a comment and you’ll be first in line for the next stage of testing.
