Most of the national/international media has been scrutinizing Twitter all weekend, specifically looking for signs of layoffs. It seems odd that this person would have scooped them all on that? Not saying it's impossible or anything, but it does make me a little suspicious.
Not that I'd say use them as the only source but they've been a source for other layoffs for a long time and he's usually correct if not always. He's the author of a few Engineering books (The Pragmatic Engineer, etc.) so he gets a lot of inside information from current and past SWEs.
Yesterday it was "lay of 25% of workforce today to avoid paying some bonus thingie that kicks in Nov 1". Well, there's still couple of hours in which this may become true, but I don't expect it, and meanwhile I see the bonus angle has been silently dropped.
