I had to login just reply to this... Google Voice is used by all kinds of people. I can think of at least ten people over the age of 50 in my family alone who use it. Hell, my 81 year old grandfather has a GV account that forwards his old landline to his cell.
Almost every one of my non-tech friends uses it as well.
"PHP is easy to deploy on. That's it. That's why it's popular. It's braindead easy to go from text editor to web URL, it's braindead easy to unzip someone else's project and run it. It requires virtually zero sysops experience to be able to use. You don't even have to worry about setting those +x bits like you used to in the good old cgi-bin days."
And that's exactly why PHP is the better choice for those of us who distribute software to non-technical users.
