you gotta look at the conversion rate as well. If only 500 ppl used Pinterest years back, but 200+ people continued using it daily after 1 month, that's shows the product has very good potential, even though the total # of users is weak. That means you just gotta figure out to get more traction.
If on the other hand, you find out only 1 person is still using it after a month, that means it's a product fit problem, and sticking to your guns is probably futile.
