informal presentation(s)

Although I can't speak for every presentation (since not everyone has finished yet), after seeing about three presentations I was struck with a particular thought: how interesting it is that there is always someone out there who wants  to read about something, something that might not interest me at all.  Living in my own world as I do, I am so eager to assume that everyone has the same tastes as I do, and more importantly that everything I like is everything that is good and right and perfect.  But of course I'm very very wrong.  

For instance, the first presentation was on "Catcher in the Rye".  I found that book to be really mediocre (even though I wanted to like it!), but there must be some reason that it's so famous.  Another presentation on a book I'd never heard of, Three (?), was interesting to me because I know if I saw that book in a bookshop, I'd never even pick it up (not trying to be a snob here, but it's true!).  I imagine it having some overdramatic book jacket that would immediately turn me off (think Dan Brown books here) and if by some strange twist of events I actually read the summary, I am positive that nothing would tempt me to buy it.  This is not to say that the author or the story are "bad", I just know how incredibly picky I am, and maybe thats a bad thing.  I guess the informal presentations are somewhat of a revelation for me; that everyone likes what they like and I'm a little bit mean.
