I think a lot of the responses here call out some definite omissions in this article (detailed analysis, the preparedness of certain companies, etc.). All of these points are valid, however, I don't think the concept of another bubble should be entirely dismissed. The thing to pay attention to does not revolve around the major companies like Facebook. The focus, rather, should be on the smaller companies that seem to get ridiculous valuations and investments for seemingly cheap ideas. Yes, Angry Birds is great but millions of dollars in investments? The bust will come from mindless investments like these. People will get bored with this game or that app and any dev that can't keep up will find themselves having to answer for insane investments that went nowhere. Luckily, like some have said, we've learned from the past in regard to bigger web firms, but until recently, "small business" didn't have a large voice in the web. You love the bakery down the street, but are their cookies worth millions? Probably not.<p>We'll see.
