I have experienced working for startups and large businesses. In my experience I have preferred working for large businesses. For me, I actually find a lot of the "perks" of startups to overall be worse for the environment. Sure, I can show up whenever I want and dress how I like, but overall is this really a good thing? Or does it just trend toward laziness and lack of personal responsibility? What's so bad about a little structure -- I grew up in a structured educational environment and learned to thrive in it.
Beyond this though, what I really like about larger companies is the expertise at my fingertips. I think I'm a pretty good programmer, but I can't do everything, and I don't have the experience to be good at everything.
At Corporation A, adding a new feature requires the following process: marketing identifies a need, project manager creates a plan, software architect decides how it should be implemented, programmer implements the feature, designer spruces it up, QA ensures that it is correct, and sales creates a pitch. Money rolls in.
At Startup B, it works like this: Investor X identifies a need, Investor Y disagrees on implementation, 95% of time is spent discussing exact wording instead of the usefulness of said feature. Programmer implements it, no one remembers what it was for, it gets dropped at the next redesign.
People say they don't want to just be a "cog in a wheel", but I see nothing wrong with being a cog in well-oiled, efficient machine. I find it very satisfying to be a small but significant part of something larger than I could ever create on my own.
I'm really impressed by this site. Huge selection of music and a very friendly UI. I like how when you add a song for immediate playback, it prepends it to your queue instead of overwriting your queue.
Facebook Connect / OpenID would be nice. Also, when I signed up with a taken username it gave me an "unexpected error" message, a bit sloppy.
