I dunno. I think when we're talking "IT", no, I don't think that cloud labor will make a difference. However, for other work, like proofreading, QC, or medical record coding, I think it makes perfect sense. Rather than bring on a full-time staff, just outsource the work.
It's not perfectly ideal for most IT projects, but in many other fields, I think it'd be great-- IT would just enable such a move.
