Seriously, I worked at a startup for a year, I didn't like the direction it was going nor my roll there. I got a new job which was a step up from where I was before the startup. Honestly, in todays economy in the United States, I see very little risk for me joining a startup. I work for one of the top 5 largest software companies in the world but I'd certainly go work for another startup. It's not like they aren't giving me full benefits and a 401k. In fact, the perks are sometimes better at new startups!
