here couple of presentations on why foursquare chose lift:

https://docs.google.com/present/view?id=dcbpz3ck_24f3v83ggz http://www.vimeo.com/8057986

keep in mind @ time of presentations, foursquare had 1 full time engineer (harry guy giving presentation) , 1m users.

foursquare has been able securely scale lift , mongodb. see comment foursquare's security: http://twitter.com/#!/rasmus/status/5929904263

and of course, foursquare put lift in space: http://yfrog.com/86ul8p

the folks @ http://openstudy.com have tremendously cool real-time multiplay online learning site. have done 1 full time engineer , couple of interns.

the folks @ http://vibe.novell.com have built powerful, scalable system on lift (although have fair number of engineers working on project.)
