Over the next few weeks, you will see a new byline on TechCrunch. We are fortunate to have tech journalist and blogger Sarah Lacy filling in as a guest writer here over the next few weeks while Michael takes some much-deserved time off.

Sarah is the author of Once You’re Lucky, Twice You’re Good: The Rebirth of Silicon Valley and the Rise of Web 2.0 (available at Amazon), she is the co-host of Yahoo’s Tech Ticker with Henry Blodget, and she still writes the “Valley Girl” column for BusinessWeek, where she started out as a reporter.

As I say, we are lucky to have her. Please give her a hearty TechCrunch welcome.
