How often I should be using const? Is it useless/overrated?

Yes, that is true (about the differences).

But Scott is very specific about it not being langauge specific. 
His guidelines are engineering guidelines.

e.g. "You're saying in your experience, the cost of the policy to 
type const all those times just doesn't pay for itself. If that's 
been your experience, then that's fine."

In other words, he is saying, the decision to use const or not, 
is a tradeoff.

Software engineers make tradeoffs, all the time. It comes with 
package.

So the answer to your question is, use it when it has a payoff - 
for you.

That's the same answer I gave to you for getters/setters ;-)
