Sometimes it's not always possible to give a usable but also descriptive name.
For example, compare "join.delay" to "join.delay_between_joining_each_channel" - a hypothetical property for allowing us to set a delay between joining each channel in the /join command.
Of course Khaled will probably go in a completely different direction with mIRC, but I like the fact that Firefox supports both a simple options dialog, and an advanced one for fine-tuning.
