I'm not intimidated, and the things you mentioned aren't that complicated. what I don't get is all those stuff about what makes a font good. I can spot out flaws in ux, recognize a good ui solution from a bad one, and I see when something falls off the grid, ohter than those technical sides I like photography, illustration and many other forms of visual art, etc., I enjoy looking at good type, but with all of that I have literally no idea why designers say arial sucks (I know comic sans suck though, fortunately). what I always do with fonts is basically a negative selection so the end result is legible and doesn't look awful for my taste, but I'd f.ex. find problems mixing serif with sans correctly (serif is in general a mystery to me, I use sans as a safer bet).
this presentation I watched some time ago is cool http://www.organizedwonder.com/videos/310 although as with arial, I couldn't tell you why helvetica is bad.
