note: i can't sign any NDAs or anything, i invest in a lot of companies, etc. so please don't think that any idea you send is really that important…

Not that he's wrong, but just an example of how he comes off as abrasive. The "so please don't think that any idea you send is really that important" just serves to belittle everyone else's ideas (while his ideas are "killer").

The startup community generally embraces the "execution is really important" mantra, so just stop it at "i can't sign any NDAs or anything, i invest in a lot of companies"

From his perspective, it's much better to filter out the people who are sensitive about such things right away, by being 'abrasive', than to spend a bunch of time talking to people nicely only to find out they're incompatible with his style later.

He does come off as abrasive but I can understand why he worded it that way. Lately people with "great ideas" are coming out of the woodwork like rabid animals. He's probably just tired of it.
