Well, Blue Moon is owned by MillerCoors, so it isn't really a micro/craft/whatever beer. I like it, however. Sierra Nevada makes good beer, too.
Nothing wrong with knowing what goes into the making of what you're drinking- learning that sort of thing is how you figure out what you like and how to make finding new stuff less of a crap shoot. I'm not at the level where I know about hops varieties yet, but I'm getting slowly more knowledgeable.
The key is to know your audience- just like I don't talk about selvedge looms with people that wear Gap clearance jeans or the relative merits of 2824 v. 6R15 movements with people who don't wear watches, I don't geek out on beer with people who drink Budweiser.
That way the glasses stay on the table, rather getting shoved up one of my bodily orifices...
