Yeah, I pretty much use it for all our internet services, except the ones where you need a large file system or the government / vendor is dictating what I can use. It works well, is pretty easy to upgrade every six months, and patching is a whole lot easier these days.

For the big file system I use FreeBSD with ZFS, and we have a VMWare server to hold all the evil I am required to keep in my server room. The fact I have some damn government vendor who hasn't validated their product on anything past Windows Server 2003 is a little annoying.
