The tech IPO market isn't waiting for Google to breathe some life into it. Since the beginning of this year, 11 U.S. tech companies have gone public, a WSJ.com article reported today (subscription required). According to Thomson Financial, during the same period last year, none went public. Add to that list 13 more companies that have filed to go public since March 1, including Blue Nile Inc. and salesforce.com.

Why the push to go public? VC's are looking to recover their investments in privately held companies, and many companies didn't want to get "lost in the shuffle" of a Google IPO, as CFO James Walker of AlphaSmart Inc., which went public in March, noted in the article.
