Twitter flight invite page is built in ColdFusion

Apple's Investor Relations website is also built with ColdFusion - http://investor.apple.com/sec.cfm - which is mostly likely not built by a consulting service.

I'd bet that neither site uses Adobe ColdFusion, but rather the Railo open source engine - http://www.getrailo.org/

The perception is that most developers that have built applications in CF have moved on to other languages and frameworks like Go, Clojure, Ruby on Rails, Django, Python, and Node.js.

While app development in CF has been on the decline for several years, there is still a very solid CMS on the platform (Mura) and is used by Intel, Nationwide Insurance and few other high profile companies and colleges.

What I found the most interesting was the use of "fuseaction" in the url - https://www.twitterflight.com/?fuseaction=reg.Apply

This is a convention that was used by the Fusebox framework, which has been defunct for quite a long time.

This is not that interesting. Marketing pages like these are usually outsourced to agencies. This doesn't suggest that Twitter itself will be moving their main stack to ColdFusion.

FYI. Just because it's a CFM extension, doesn't mean that they are using ColdFusion (which is Adobe's CFML engine). They could very well be using Railo (http://www.getrailo.org/) or OpenBD (http://openbd.org/). Both of which are free, open sourced and magnitudes faster then ColdFusion.

As a longtime ColdFusion user, and maybe one of the 3 of us who is remaining, I found this to be interesting.
