Facebook has over 800 million users, so they say. 300 million of them are using Facebook on mobile devices, and that number will only continue to grow, as long as Facebook remains the kind of social networks.

Brittany Darwell at Inside Facebook has discovered a couple of new features for Facebook’s mobile site. One (in testing) is a recommendation tab for pages. With this feature, the user can write and read recommendations on Pages, similar to a feature launched on the desktop version not too long ago.

The other feature is the addition of filters on mobile page walls. When a user visits a page, they can switch between all posts and page posts (all meaning including those from users). This has been a feature of the regular desktop version fo the site for a long time, but it hasn’t been an option on mobile.

It would appear that Facebook is looking to make the mobile experience more uniform with that of the desktop experience. The Android and iPhone apps were recently redesigned and greatly improved to do so.

Word is that the company will introduce mobile ads in the near future.

Snaptu, which Facebook acquired last year, recently announced that it would be shut down so the team could focus on Facebook’s mobile experience.

Mobile is obviously an incredibly important element of Facebook use, and it seems like Facebook hasn’t put nearly the emphasis on it that it should for a long time. Perhaps that is changing.
