Facebook forewarns that FBML, or Facebook mark-up language, is a dying language. This will force companies with existing Facebook apps to move it or lose it. On January 1, 2012, Facebook will no longer support apps coded in FBML – so, no bug fixes, ever again. More ominously, on June 1 all existing FBML apps – whether bug-riddled or still fully-functional – will vanish, along with user data that, until then, lived in them. Facebook giveth and taketh. But, if you proactively convert your FBML to HTML on an iFrame, all’s well. Not sure if your Facebook app’s days are numbered? Dan will tell you how to tell:

Call it spring cleaning, as Facebook is purging old tech in favor of something newer and, for them, much more nimble: HTML and iFrames. Whereas FBML hogs HD space on Facebook’s content delivery network, iFrames are hosted on each user’s server.

Sure, FBML apps won’t necessarily break right then on New Years Day, but if they do, there’ll be no easy fix. To be clear, FBML apps will soon no longer exist – let alone work – on Facebook Platform; all FBML endpoints are history, come June.

Now, the good news: There’s time to be proactive, and I’m surrounded by nerds who assure me they can make everything alright. At The Nerdery we’re collectively versed in virtually all programming languages (and can practically write Haiku in them), so converting FBML to HTML is right up our alley – whether we were the original developer of your Facebook app or not. Let me hook you up.
