Yep. It's been a steady producer for as long as I've had it with two major hickups, the first (of course) the .com crash, the second the death of iBill.
It has survived both, the first by changing from an advertising driven model to a subscription model, the second because I'm in close contact with someone that owns and operates and IPSP so I could switch on a moments notice.
I probably aged a couple of years for each of those.
