No but it would be an idea!
But seriously, what I was saying, and what you will find elsewhere (you alluded to it yourself when you mentioned Barclays) is that when you come into money via some level of chance rather than skill, what you do with your money should be guided by your skills. If you earned the money entirely via your own efforts then you will have a diverse portfolio, you will make decisions about investments in the areas you understand, but you will use other peoples talent to grow your money outside of those areas.
Say you are an amateur metal detectorist, you find a huge horde of gold and get your 50% of it. Now, do you take it upon yourself to go into the precious metals market, or do you buy yourself a new metal detector and invest the rest in funds managed by people who at least supposedly should understand the investments they make and have a proven long term track record of a decent ROI. My thoughts were just that they basically seem to have found themselves in a very good situation and seem to be taking very large risks (bitcoins and internet VC, yes you might find the next twitter or youtube or amazon but honestly the odds are stacked against you and even when you do hit it big how long will it last? AOL, Yahoo, Myspace even Hulu now is looking a little suspect). I guess there is the easy come, easy go mentality, but personally I'm not sure I would be taking as many risks using my own knowledge. VC is a tough field, even the best investors lose more times than they win (the key is that they make more when they win then the sum of their loses). It's their money and their call :)
