The worst thing about VC's is their herd-like behaviour. You work hard to get your biz funded and as soon as the valley gets wind of your funding, all the other VC's immediately fund X other copy-cat businesses (almost seemingly without regard to viability of the original business model). And given a16z's huge reliance on PR, I'd argue that if they funded your biz, you'd then have even more copy-cat funded competition than if you went with a more low-key VC.
