I'll take the contrarian stance and say I'm not really impressed with the list. There are some that may be good, but there's not much new. Mostly me too products.

Perhaps my expectations are too high.

I don't like any of those categories.

1st group: starfucker douchebags, properly characterized by the OP. Prone to serve the "high-status" set they want to join as soon as they have access to those people, and therefore a liability to anyone who wants .

2nd group: contains a lot of clock-punching mediocrities, also correctly portrayed by OP.

3rd group: driven by empty ambition, likely psychopaths. These people are responsible for the "next quarter" mentality that has ruined the US and shaken the world economy.

What unifies types I and III is the narcissistic character of a toxic and dangerous personality. What differentiates them is low (I) vs. high (III) self-image. The stronger self-image of the third set makes these people more dangerous, IMO.

What about?

Group 2+: Those who want to be comfortable, so they can spend their mental energy on things that are actually interesting and useful. These are people who wouldn't mind getting rich, but are more interested in solving interesting problems and making the world a better place than in having toy X at age Y.

There are a few gems in there that I'd like to see more of (etacts for instance), but overall I'm dismayed by the sheer volume of SV navel-gazing produced twitter junk.

I'd love to see more ideas around PG's list of things he'd like to fund being presented instead of yet another "social collaboration because what else is there?" startup.
