I think saying that AC is kind of a DIY program makes no sense."
Wow, was I misquoted.
Well, not exactly misquoted...just misunderstood.
Remind me, if I have a thyroid problem, not to use Dr. West.
You can see from the blog that he did his fellowship at the place we Maryland grads sometimes refer to as "that East Baltimore Medical School". No guarantee of tech savvy (or common sense, for that matter) comes with the certificate.

And Bert, you worried YOU were being a smarta**!
using a cloud solution...well it makes sense for him. I suspect for many others as well....it's very tedious to install & reinstall every bug fix version. What if AC could work on the versions, and push out the solutions when I log on every day? Most of us can keep an internet connection going. And the rest goes away.
Or what if it wasn't AC: what if it was someone we trusted with technology issues who would run AC on his own servers, only upgrade when he felt the new version was stable, and leave us to simply deal with stripped-down hardware providing internet access from our offices. Could that work?
