The final tip being "use the tool I'm selling" makes the preceding 10 seem a lot less compelling. I'll stick to testing my code in prod, thanks.
At Mozilla, we use GitHub (for project hosted on github, such as Gaia), and splinter [1], that integrates with bugzilla. I know there is an ongoing effort to switch to reviewboard [2] at the moment, as we feel our review tool should do more that what splinter is capable of doing.

IBM stuff, however... well, I've mentioned my feelings on their software on HN before. They're still selling Lotus Notes and Clearcase - I'd be very careful before taking anything they've built/bought.
