Exactly what Facebook plans to debut later this week at its f8 conference isn't clear, but it's reportedly big, and will likely reshape the site's core experience with new "read," "watch," and "listen" buttons.

With the new battle cry, "Read. Watch. Listen.," Facebook is expected to "unveil its next massive initiative to socialize the Web," reports All Things D. "A key focus of this year's annual event has been well reported: Content."

The supposed "motto excites me because of the promise it holds that Facebook will fully embrace multimedia," ReadWriteWeb's Richard MacManus writes. "But that has some major implications, which will affect many in the Web ecosystem."

 "As the New York Times conveyed this past weekend, Facebook is planning for ways to surface personal content better," writes TechCrunch. "And we've heard from a source that Facebook will introduce new buttons on the wall that will begin introducing some granularity to the ‘Like' concept."

"The granular feedback could also power the quietly launched Broad Category Interest targeting available in Facebook Ads, which lets advertisers target anyone with interests related to a selected subject rather than targeting those with specific Likes," Inside Facebook suggests. In addition to "Read," "Listened," and "Watched" buttons, Facebook is also reportedly testing new social commerce buttons like "Want," TechCrunch adds.

"This ties in with murmurings CNET has heard about Facebook's desire to help its users find others who like what they like and then discover additional songs and other content based on that," CNet writes.

"The upshot of all of this is that Facebook is embracing sharing media on its platform, after a long time largely focused on people interactions," ReadWriteWeb's MacManus adds. "The social networking aspect won't go away of course, it's simply being extended to enable people to share what they're consuming."
