An anonymous reader writes "Do you think so called 'rock star' developers are necessary at every company? Personally, I don't think so, and I equate it to not needing a college degree to work at Walmart. If you give every problem a complexity value from 1 to 10, and your problems never get higher than a 6 or 7, do you need people capable of solving the 10s? I work for a large software company and I'd rate myself a 7. There are more technically proficient developers, but I don't have an ego about my work, I work well with coworkers and customers, and I bring people up around me. Most 'rock stars' I've seen have been difficult to work with. Most of them are no longer with the company because they were terminated or quit for more money. Is this usually the case? Is it worth the trouble? (Note to any managers reading this: if you have a rockstar who is a pleasant person, pay them well; they are very rare.)"
