That is some funny shit. I wonder if they can/will retract.
See, there are some ideas that one *should* be dismissive of in a brainstorming session.
Or, how to do a digital task if you can't parse your way out of a paper bag (hint: parsnips).

Amusing. BITD one would have used an Intersil ICM7217 or something like that.
Unlike a lot of what the trade rags publish, this jokey circuit would probably work at some level, except that they need a resistor between the inverter's output and the crystal tank. Otherwise Zout of the gate will destroy the Q.

Then they're dreaming if they think they're going to tune the capacitors with a two digit display of MHz, and their dumb 2907 doesn't come close to 10ppm.

Has this guy not priced frequency counters lately? They're rather inexpensive. And (ehem) a bit more accurate than the suggested circuit.

The first thing you need when measuring the frequency of a crystal is an accurate time reference. Obvious thing to use is a crystal, but you'll need to choose the appropriate capacitors to go with it, so best measure its frequency. So you'll need an accurate time reference...

Maybe, engineering is making what you want out of what you have.
Did someone (root) rutabaga your funny bone?

POT1 and POT2. Grrrrr.
