And here's how to start. Read this editorial about Facebook:
I haven't seen this level of irrational exuberance since I was Pets.com.
Here's the best part:
Facebook reached 500 million users in July. There's been no update since, even though the company had meticulously documented every new 50 million users to that point. Might the curve have crested? And let's not even talk about the fact that they don't really make much money per user — a few dollars a year at most. (Its estimated $2 billion in 2010 revenues would amount to $4 per user at that base.) I certainly haven't spent any money on the site, despite being a fairly regular visitor. And any advertiser who is trying to target me on the social network is wasting their money. But that's just me.
Nope, that's a lot of us...
