Actually, I don't mind so much having an IC knowledge of things in Luceti because it is ICly possible to go back and read/listen to posts made before your character arrived (except the older Lucetilocked posts). As long as something is stated on the journals and not filtered (or your character can hack the filter), it's able to be known IC. There's definitely a ton of information if your character wants to go looking for it, though just as much useless information as well.

Of course, this does require quite a bit of a time commitment since it is over 4 years of stuff. A character like Ginia who is everywhere, volunteers at more than one place and is often on missions is not as likely to have that sort of time as a character who isn't as sociable and enjoys gathering information in that way.
