My last job was in a corporate cubedom for 4 years. Not a massive company, but a few 100s of employees. We held weekly code reviews at one point. Also bosses do have a habit of suddenly believing that if they help code the project might run quicker, so they ask for svn access etc, then break everything :)
We had so much Sarbanes-Oxley bs anything seemed possible. "Oh you can't use an IM client that isn't approved by us, as it's against S-OX". (Approved by us meant that they paid some inferior crappy IM company to install their client on all company computers. Then they paid a fee per user) Nothing like corporate waste :)
You don't work in a corporate environment, do you?
If you're working for bigco, swearing is probably not going to go down well with your boss, or co-workers
Since few bigcos I've ever worked at ever do code reviews, how would they even know?
After spending many years in corporate environments, it's easy to spot those who haven't when they post comments about corporate environments.
