Re: Did they ever explain how Geordi...
I've always assumed that Geordi graduated the academy as an engineer, but early in his career was convinced to switch to the command tract. Which was where he was when Picard met him. He probably was torn between going back to egineering or taking a the pilots position on the fleets flagship when Picard offered him a slot on the E. Picard no doubt knew of Geordi's engineering background and used him in that capacity when needed. When the CEO position opened up Geordi and Picard probably jumped at the chance to place LaForge there.
The boring one, the one with Khan, the one where Spock returns, the one with whales, the dumb one, the last one, the one with Kirk, the one with the Borg, the stupid one, the bad one, the new one, the other one with Khan.
