This article is very confusing to me. If we are concluding that startups are laying off due to funding squeeze, how is that San Francisco actually saw a decrease in lay offs ? SF is where most of the startups are based. Also, it says that layoffs totaled roughly 3000 in 4 months. Which comes down to 750 a month. Compare this to what the article said later that 32,000 jobs were lost per month during the recession. Finally, I couldn't figure how many jobs were added in this period, to get a context of the layoff percentage. Seems a little alarmist
