This thread is full of nasty comments about sama and his blog post.
To those of you attacking him, remember that you're talking about a man who has already proven himself to be one of the most disruptive entrepreneurs SV has ever seen, despite still being relatively young. When Sam was a fresh Stanford dropout, he built Loopt, the very first location aware app, which spawned dozens of imitators, including Foursquare and Gowalla. It also doubled as a dating app popular amongst gay men and easily beat Grindr to market by a decade.
If sama says Jeremy's claim is baseless, then I'm inclined to believe him, on the strength of his reputation and accomplishments alone.
Edit: Could the downvoters at least explain themselves? Is defending YC or sama enough to deserve downvotes now?
