Ah, but it's quality that counts, not quantity. If ESPN's coverage includes plenty of live matches featuring (gasp!) some non-American players on either the women's or men's side, then you can feel entitled to acclaim their coverage.
The point is, people are selling themselves short with this whole "it's better than nothing" attitude. True, it may be better than nothing, but it's also worse than most. Letting them know that you enjoy their coverage will just give them the green light to continue in exactly the same mediocre vein, whereas letting them know what their faults are BUT also suggesting improvements that could be made will at least point them in the right direction. The key is not to emphasise what's being done badly, but to emphasise what could be done better.
Say it Quietly, I'm White but I'm Really Rather Contrite
