Mahalo is equated with spam in the eyes of many HNers (including me), and JC is seen as the promoter of said spam.

EDIT: Why the hell is this getting so many upvotes? Because it's easier to read? Upvote, instead, some of the comments with actual fucking content.

EDIT2: Also, while I think (much of) Mahalo is spam, I respect Jason and his business, and wish him the best of luck.
