Facebook is testing a new blue Like button. Users have spotted it showing up on the Web, but not on the social network, which suggests the potential change would only be affecting the website plugin. Here are before (left) and after (right) screenshots, courtesy of OfficialWire:

Facebook confirmed this is a test, but wouldn’t go into any details. A Facebook spokesperson instead gave TNW a boilerplate statement: “We’re constantly testing new products but have nothing further to share at this time.” It’s worth noting that the blue button includes the Facebook logo, which is likely an attempt to further differentiate the social network’s Like button from the many copycats.

Update:

Looks like this is in fact official. The button is live in the iTunes footer here, screenshow below.
