Replace Facebook Page FBML Tab with iFrame Apps

InBoundNow has posted a quick and simple video on how to set up an iFrame app for your Facebook pages to replace FBML, which is being phased out.

Advantages


Pulling a page you create and host into Facebook allows for a much more dynamic experience within Facebook and allows you to continue to use your programming skills rather than having to learn the Facebook API.
Since you are pulling in an existing page, you can code and develop on your live site without having to log into Facebook, which adds a layer of security to credentials (i.e., some people can administer Facebook, others can access the live site).
You don't have to use trial-and-error with the code you enter in FBML being stripped out by the parser.


Disadvantages


It adds a layer of unnecessary complexity if all you want to do is create a static page of content and images.
You must have a webpage to show in the iFrame. If you're a small organization without a website or using a free service like a WordPress blog for your web presence, this is a problem.

It will be interesting to see 6 months from now it iFrames have fully replaced FBML or if we see an FBML-lite option still available.
