Microsoft R&D delivers again. Name one feature in so.cl that wasn't a copy of what they already saw somebody else do, except given a slightly different name or capitalization in order to shave off the boilerplate. Is there anything left from Google/Apple/Facebook/Amazon/Sony for them to copy, er, I mean, innovate in-house? I also bet they'll claim it took a team of 50 people and cost $1B to create. Because taxes and accounting, of course.
