Nathan said:What percent of Trek Lit is Crap?
Well, since Trek Lit ⊂ Everything, by Sturgeon's law I would have to assume 90%!

J/K, of course. Based on my own personal tastes, if we assume about 600 books, I would probably rate the percent of actual "crap" around only 1 - 3%. (Opposed to just "meh", which would be a lot higher.) But keep in mind that a) I haven't actually read all of them, and b) I may be inordinately easy to please!
