"Business social networking site LinkedIn is set to go public on Thursday, marking one of the highest profile Internet IPOs since Google\u2019s in 2004 and spurring talk of whether we\u2019ve entered another tech bubble as valuations for startups continue to climb.\nEarlier this week, LinkedIn raised the price of its offering by 30%, in turn valuing the company at north of $4 billion.  As WSJ noted, the increase was the biggest pre-IPO bump since 2000, when the last tech bubble popped.  (As a side note, 63.67% of our readers thought Microsoft paid too much when it bought Skype for $8.5 billion last week).\nThat said, LinkedIn does have significant revenue ($243 million last year), is still growing quite fast and is increasingly profitable, something that can\u2019t be said for many of the dotcoms of yesteryear.  Here\u2019s how its likely price to revenue ratio stacks up to some other publicly traded Internet companies (data via Yahoo! Finance):\n\nRenRen: 65.2\nBaidu: 33.1\nLinkedIn:  16.4\nSalesforce.com: 10.4\nGoogle: 5.5\nDemand Media: 4.4\n\nTaking all of that into account, would you be a buyer of LinkedIn at its likely IPO valuation of $4 billion?
