Assuming that the recipient can keep a straight face?
EDIT: Perhaps having a16z as the only VC in your seed is a very bad idea. Chris Dixon (now a partner at a16z) cautions enterpreneurs against the risks of having a sole VC in your seed round:
"I can think of about 15 founders I’ve spoken to recently who tried or are trying to raise Series As but are seriously hampered by the fact that a big VC invested in the seed round but isn’t participating in the Series A."
A large micro-investment portfolio.
Anything in this portfolio is sort of a tip of the hat from a16z, a micro-endorsement that messages: "we've got our eyes on this company."
I'm confident that these six new Pinboard/Ptacek/A16Z companies will have excellent return on investment.
Humor aside, there are many smart founders but being brilliant and being money-minded are orthogonal.
Heck, I will wager $37 that submitting your startup idea to HN will get you more exposure than posting on Pinboard's blog.
