Some people take this generous treatment for granted, and leave. It hurts to see your friends at work move on, but that's how this industry is. Good memories were made and cool projects were shipped.
I think diversity initiatives have gone a little too far here. Suddenly there seems to be disproportional amounts of women getting hired into management. I think diversity is a good thing but it feels very, very forced. Some women teamed up (after the "Frat party" incident) to push alcohol out of the workplace entirely. It wasn't 100% successful, but is scary that people team up to kill culture. No more happy hour beer pong, and most floors are now void of the cute beer fridges. Let me assure you, they weren't abused. They were mostly used on Fridays after work, or after shipping something cool as you watch the results & feedback stream in. Work goes on, but it's now missing the spark and edge this place used to have. It's matured and not caters to a few whiney old people who wave the PC & diversity wands.
I think the hiring bar is dropping. Although they say we only hire very passionate people, many have argued to hire people that didn't even bother to sign up before flying across the country for the interview. That brings me to my next point. Some non-passionate people were hired for their intelligence but not their personality or passion for the product. They're the minority, but they bring in some likeminded people who don't talk much.
There is also a lot of bureucracy, and some managers have way too many direct reports. It's easy to get lost between the cracks, and easy promotions could get dragged out forever.
Stock is down. Wall Street needs to realize what Twitter is about, why Facebook is jealous, and how to empower Twitter. Measuring DAUs and other social network stuff isn't the best. Or so we've been told.
