Even if OP doesn't I suppose I can give it a shot, on the topic of effort posting.
One feature of the manga is the frequent reviews published in the Genshiken fanzine, where each character gives their own unique take on whatever the club is currently obsessed with. Not only does this paint a pretty interesting picture of an imaginary piece of media, but it also acts as a method through which club members are further characterized, as their taste and methods of expressing it are reflections of themselves. To me, there's something interesting about misfits trying to express their reason for liking things which are by and large ignored or outright maligned by society, and in doing so slowly gaining confidence, which is eventually leveraged into forming a connection with others. Even if their reviews aren't particularly well-written or profoundly insightful, there's an inherent value because they put so much effort into expressing the interest they hold for the media they are discussing. (and their passion is contagious)
Genshiken is not just good, its relevant to imageboard culture because its a place to express feelings that may not be accepted or tolerated elsewhere, and in finding this place each character ultimately learns to truly let loose with their passions, and that's about all I can muster up to say about the merits of Genshiken and effort posting. And obviously the manga would have probably sucked if the characters just made posts online that read as "Just finished Kuji-Un, what did I think about it?"
