What's one thing you wish you'd known before joining LinkedIn?

how much the customers are angry with LinkedIn for annual price increases and "repackaging" the same exact products into new names / calling them something completely different when the functionality / benefits have not changed at all. I wish I also would have know how many managers have not been promoted from within - since I'm used to being able to go to management to ask questions about how to do the job and unfortunately my entire team of 15 was unable to do this with my manager. Same situation occurred with two other teams on my same floor.
