Some time after the dotcom boom turned into a spectacular bust in 2000, bumper stickers began appearing in Silicon Valley imploring: \u201cPlease God, just one more bubble.\u201d\u009d That wish has now been granted. Compared with the rest of America, Silicon Valley feels like a boomtown. Corporate chefs are in demand again, office rents are soaring and the pay being offered to talented folk in fashionable fields like data science is reaching Hollywood levels. And no wonder, given the prices now being put on web companies.<\/p>\n
Facebook and Twitter are not listed, but secondary-market trades value them at some $76 billion (more than Boeing or Ford) and $7.7 billion respectively. This week LinkedIn, a social network for professionals, said it hopes to be valued at up to $3.3 billion in an initial public offering (IPO). The next day Microsoft announced its purchase of Skype, an internet calling and video service, for a frothy-looking $8.5 billion\u201d\u201dten times its sales last year and 400 times its operating income. And those are all big-brand companies with customers around the world. Prices look even more excessive for fledgling firms in the private market (Color, a photo-sharing social network, was recently said to be worth $100m, even though it has an untested service) or for anything involving China. There has been a stampede for shares in Renren, hailed as \u201cChina\u2019s Facebook\u201d\u009d, and other Chinese web giants listed on American exchanges.<\/p>\n
