Here's what I would be curious about - Does anyone have any stats/history about companies that have in the past gotten the "big valuation/major PR" during their initial launch/funding and ended up actually becoming a $billion dollar business? I feel like the pattern is usually the opposite -- Google started as a grad school project and was funded with $100k (before Sequoia put in $25M). Facebook started a few years ago without a ton of fanfare and $500k, etc. I feel like everyone is predicting failure because usually when companies and investors so loudly proclaim brilliance/future success in such a public way, we're used to seeing failure in the end (Cuil)... Curious to hear any examples folks might have....
