As a whole, Facebook (News - Alert) has been undergoing a ton of changes lately – venturing into new territories and growing even larger than it already was. For one, it's preparing to file its initial public offering soon, which could raise as much as $11.8 billion. It just purchased the mobile photo-sharing platform, Instagram, for $1 billion a while back, and to top it all off, announced the oncoming launch of its App Center.

Regardless of all the flack that Zuckerberg caught for wearing a hooded sweatshirt to address investors at the IPO roadshow's stop in New York, Facebook is still going strong and has a ton of things in store for the future.

The most recent update brings the social network's mobile site more up-to-date with smartphone browsers – optimizing pictures and posts to span the width of the screen, enhancing the whole experience in a dramatic way.

Previously, Facebook mobile seemed more like something designed for feature phones and lower-resolution smartphones, in the sense that users were stuck with tiny thumbnails and a single vertical column with all the posts crammed together. There were a few short-lived updates that made the Web-app take on more of a full-fledged mobile app persona, and this update builds upon that concept.

With the average, reasonably-priced smartphones only offering around one or two gigabytes of internal storage, users don't want to download an app for every Website they commonly visit. More than that, it seems kind of redundant to rely on an app that has to be constantly updated and only serves one purpose when the same experience can be attained by firing up the browser and navigating to the mobile site.

Not to say that the app has been abandoned in any way though; it received the same updates as the mobile site yesterday as well.

The mobile Web has grown up a lot since 3G and LTE smartphones have started taking over – there's a lot of potential for companies like Facebook and Twitter (News - Alert) to roll out feature-rich browser-based mobile clients.
