JIRA can a great tool, but that has nothing to do with mongodb nor the quality of the code the team produces.
The connection to mongodb is that their team chose JIRA and continue to use JIRA. I was implying that by choosing such a horrible bug tracker that you must question their code for mongodb.
In retrospect I probably should have added a smiley face or not made the comment at all, since it's entirely possible they didn't have a choice in the matter and JIRA was chosen for them by a pointy haired boss. After all, I was forced to use JIRA at my previous job and the quality of code I produced and technical decisions I made were not affected by choice of bug tracker. So to any mongodb devs reading this who may have been offended, I am sorry and I feel your pain in having to use JIRA, I hope you can escape it soon :)
