http://m.mlb.com/ http://m.mlb.com/ uses a hybrid Freemarker / Groovy / Java framework called MVC+GF. During the 2009 season it was able to scale with out issues during peak hours (9th innings, etc). That's hundreds of requests a sec a server - pretty cool. Groovy is used cause it has closures (java doesn't) and is simpler and easier than Scala.
