Leading the day, we have TechCrunch reporting on layoffs at Groupon. They are dropping 1100 employees and closing operations in 7 countries. This could be a signal that the deal companies could be in trouble. Johanna Rothman continues her series on resource efficiency and flow efficiency. Sam Altman gives us an excellent post on unit economics in the world of startups. Brad Feld touches on the more personal side of the job in his post on anxiety. He is one of the few high profile people in the tech industry that frequently talks about the kind of thing and it is always worth reading.
As always, enjoy today’s items, and please participate in the discussions on these sites.
