With their data replicated over so many servers, I don't think Google place the same emphasis on data integrity as us mere mortals. Their server environment is unique and it is difficult to draw conclusions from their decision.

I would still be wary of ext4 for the moment for a production server, its reputation and novelty remain stumbling blocks to adoption. Give it another year or two to mature, and we'll see if stories regarding its tendency to lose data is undeserved. If ext3 works, then why jump too fast?
