Today's startups vs the dot-com bubble (interactive viz)

Interesting piece.

However, this isn't an either/or bubble situation. The 2000 implosion was a disaster, but that doesn't mean that anything with slightly improved metrics is safe. You can create mad revenue when you're spending $1.00 to make $0.50 like Groupon is doing.

It seems like we are not in a bubble, excluding Groupon.
