in my .bashrc for 20 years. I just don't see the appeal of persistent history. And I've seen too many intrusion pastes where passwords and databases are pulled out of the bash history file.
In a work environment with many complex shell commands to perform daily tasks shell history is the most efficient way to repeat tasks with complex command lines performed weeks/months ago. Documentation, wikis etc are always slightly lacking/stale and are less effective than simply seeing how you did it last.
