I think many people might misunderstand the Queen concept (or I misunderstand it but feel superior to others, could be

). The Queen is just another representation of the Borg. The
Hive Mind IS one single individual, with needs, desires and even emotions (think of each drone as a brain cell). And it is lonely. And in a tragic irony, the giant mind felt accidentally attracted to a human being it just assimilated: Picard. So it decided to create a humanoid representation of itself: the female Borg "Queen". And it decided to give Picard more individuality than the usual Borg drone, so they both could be together.
That's also why the Queen survived the destruction of the Borg Cube. The giant individual called "The Borg" still existed. It lost a few brain cells that day, but that's about it. And knowing that when they attacked Earth in First Contact they would run into Picard again (since the Borg called him all the time to make sure he would be there), the Borg brought a clone of the "Queen" drone with it.
I like that concept.
And Voyager pretty much ruined it. The Borg Queen shouldn't exist for the Voyager crew, there is no need for it. The Queen was just a representation chosen to interact with Picard. For Voyager, the Borg should have been just as impersonal than they were for the Enterprise crew in "Q Who?"
