Facebook [3] is developing a photo app similar to Snapchat [4], the year-old startup that puts a 10-second time limit on the visibility of a photo or video. AllThingsD is reporting [5] that Facebook's version is expected to launch before the end of the year.

Snapchat recently raised [6] around $8 million from Instagram [7] backer Benchmark Capital. [8] The beauty of Snapchat is that, as well as deleting the image from both the sender and receiver's phone, it also deletes the message from its servers.

With over a billion photos uploaded--paf! what photo? *innocent face*--on Snapchat in just over a year, there's obviously a huge market for temporary data. Now that so much of the world's data belongs to Facebook, it's not surprising the firm wants to throw users prone to sharing a less-than-modest alternative.

So, what do you think-- are you a fan of digital fading [9], also known as digital dementia [10]--which means your social media feed has a finite life-span? Or is the balls-out version--where everything is shared and nothing is sacred--more to your liking? Comments below, please!
