I can see positives and negatives to Google for Hadoop, though. Positive: more job applicants that have experience using a mapreduce-like system, which means they will come up to speed faster and with less training or mentoring. Negative: as Google old-timers vest and leave, they’ll have more ability to apply the scaling skills they got at Google to whatever startups they’re going to. I guess the question is whether or not hiring is faster than attrition.
