On the basis of his ear for random scraps of conversation, I would venture a guess that this playwright-blogger is good at his chosen craft. If, that is, you think that unscripted-sounding dialogue makes for good plays, which I generally do.
On the other hand, I recently overheard in the soup aisle of the supermarket an apparently authentic exchange that sounded so scripted, I would hesitate to put it in a play, or on a blog like Tim’s:
SON: What’s “Soup at Hand”?
FATHER: Soup getting out of hand.
Ow. One can’t help but suspect that some coaching was involved.
