Ailing Sunnyvale-based Yahoo Inc. suffered yet another setback this week after "lackluster' first-quarter results were announced. As a result, anywhere from 600 to 700 jobs will be cut. This makes the company's third round of layoffs in over a year. Yahoo product managers, it seems, are most likely to get axed during this round of layoffs. At least so says Chief Executive Carol Bartz who blunted, "We sort of had one product management person for every three engineers, so we had a lot of people running around and telling people what to do, but nobody was doing anything," Yahoo cut more than 2,500 jobs in 2008.
