There's more good than bad in this post, but Ben had to ruin it, and his credibility in general, with this:

Bottom feeding publications such as Valley Wag

Valleywag is cynical and harsh, but it has done more good for technology and humanity than all of Sand Hill Road combined. Ridicule is extremely powerful (see: Stetson Kennedy's exposé of the KKK in the 1960s) at taking down a reputable evil.

In the ongoing war between Frat Boys and People of Substance (aka Real Technologists) the Frat Boys have local advantage, because they've got better playa skillz with the VCs. It takes a continuous rash of ridicule to draw attention to the global concerns of technological advancement (also known as Real Technology) and keep us out of the shitty local maxima that Frat Boys tend to bring us to. If we want People of Substance to have a chance in the VC-funded world, we need a strong "yellow journalism" to ridicule bad actors and, thereby, clear the field a bit for the good.

If Ben Horowitz really can't see this, then he doesn't deserve to be a leading investor. Of course, this post is five years old and his views may have involved.
