For Star Trek enthusiasts, it might be a bit fun to get lost in the timelime at Wikipedia. (I've had a bit too much time on my hands lately while coping with H Pylori bacteria.) A person could really get a bit lost/obsessed with this stuff.
A question to ponder: Can a person manage Star Trek fandom along with LOTR fandom and Narnia fandom at the same time? Perhaps this is why I cannot afford to immerse myself in true fandom ... and why I have not bothered to read Harry Potter. At some point, one really has to emerge from the world of fandom and get back to everyday life--and manage the entry into fandom so that everyday life remains a priority.
