Well ... the three "700-pound gorillas" in large-scale web application 
deployment are LAMP (Linux-Apache-MySQL-PHP), "assorted Java platforms", 
and WISA (Windows-IIS-SQL Server-ASP). LMMR (Linux-Mongrel-MySQL-Rails) 
is probably in the round-off noise, and I'd be extremely surprised if 
anything that's turning a profit is running on any kind of Windows 
platform using Rails.

As far as I know, Twitter is really it, and I don't have any clues at 
all whether Twitter is profitable. I don't even know what their business 
model or "unique selling proposition" is.
