It's now May. I don't think a failure to find traction in 3 months is really a strong indicator of whether or not the product has long term potential. And whether or not that particular product has long term potential is not a solid indicator of whether or not the startup does.

And it's not very logical to assume that infrequent blogging means the founders have given up. It might mean just the opposite.

It's humorous how he chastises them for not having much traction so quickly, while also chastising them for giving up so quickly.
