Jacques, I don't see what relevant my track record has on the argument [1]. I have nothing but admiration for the two brothers. They have done impressive things for their age. My comment was directed at the spin doctoring of Silicon Valley which is likely the aggregate results of marketing effort by Ycombinator (great exit story), their other investors (same), the brothers themselves (CV building) and the general SV media frenzy ("teen millionaire" sells). The problem is that such craziness only fuels silly perceptions. Look at this post. Much of it is devoted to finding some magic process in their parenting! The story real story here is likely along the lines of: be born with good intellectual capacity (genetics), have educated parents of reasonable means in an advanced country who can provide good schooling (lottery), don't have too many social strains during upbringing (divorces, violence, drugs, etc.), enroll in an elite program (Ycombinator), and rely on the efforts of a whole ecosystem to enable PR wins. Much of the above is luck and not some kind of easily repeatable process for creating successful people. Note that this doesn't take anything way from the brothers. They still needed to follow the path, work hard and make good decisions. That's impressive but there is no magic here.
Regarding the Auctomatic exit, keep in mind that they were not bought by some gigantic company whose stock price was subject to many outside factors (like ebay - spin doctor much?). Their buyer, Live Current Media, was specifically created as a new public company for their acquisition. The stock price of the company at $2/share is almost entirely an imaginary number (no meaningful capital was raised during the founding "IPO" so there is no external validation - the first real material share transaction a few months later pegs the price below $0.2 already). Cash payment during the transaction appears to have been around $800k which was later converted to convertible notes when Live Current Media couldn't pay and had to restructure the deal in 2009. The remaining stock portion of ~$4M converts to ~2M shares (at $2/share) which then dropped to about $100k. Allocation to the four (or three) founders seemed to have been ~400k shares, so $20k on liquidity (for all of them together) [2].
During that period (new entity in 2008, restructuring in 2009), it appears that one or both of the brothers were part of the management team of the new entity (I am not saying that they caused the stock drop, just that this is different from selling a company to Google and then have Google's stock drop later).
Again, their accomplishment relative to their age is impressive. Building and selling anything is hard. But Live Current Media basically bought a domain name and paid domain name dollars for it (in real dollars).
[1] Ironically, I did sell a company for mid 7 digits (all cash), though I was a few years older than the brothers. Doesn't matter to the argument though.
[2] I know nothing about the transaction but I can read financial reports like this one: http://www.faqs.org/sec-filings/100329/Live-Current-Media-In...
