The fact that a lot of people use a particular software application does not, for a second, suggest that it's the best of its kind... nor even any good at all.

The market is largely ignorant, and therefore very vulnerable to marketing. Also, most pundits have a strong incentive to find the products of the richest software author the best (because they tend to spend the most on marketing with "independent" IT journalism titles). All this leads to incredible mediocrity in the software world.
