Arrington disagrees that the criticism has any merit; at worst he's letting himself be trolled. I guess he feels something needs to be said, and I respect
that.
Which is fine, of course. He's more than justified in defending himself. This article just isn't interesting from a "too few women in tech" angle, and you can't really generalize from what's going on here. It's fine that he wrote it, I just don't see that it warrants much attention from HN.
