I was just musing about how the definition of 'startup' has changed. I've worked in a couple plus a few post-startup small companies, but they always involved a fairly expensive piece of boutique hardware. At best, stock options might mean a decent bonus after a few years and you work as long as they pay you. You take the job because it's interesting and because it's more fun to lay track than to fix it. Using folding tables is always better than dealing with some middle managers three ring binder of yearly performance review.
Seriously, just how many startups in the last ten+ years involve anything but some sort of internet service/social media/advertising software construct with (usually) the hope of selling the company? It all sounds kind of depressing.
