I use LyX all the time. I love it and encourage everybody to try it. I usually get great results.Except when I am in a hurry and forget to change default fonts. In particular, I've been stung by the combination of the listings class and default typewriter font. Last week, I threw in a lot of R code with "<-" printed to pdf as "< ". There were invisible dashes. I did not notice and printed handouts for a group. Other symbols have gone missing, sometimes ~ in verbatim class is invisible.
It is easy to fix by setting typewriter to Latin modern or other font, but in an emergency, I always forget. You would make my life more fun if you would make the default something not-yet-known to give bad results. I'm not talking about fuzzy font edges. Invisible characters without warning are super bad. Awful. So I offer $100 US if you will change the default font to Latin modern or any other one. I know that's not much, but I am sincere. I note your FAQ already admits that default LyX fonts make bad PDF. I will leave to others to discuss that. But the default typewriter font has to go. Paul Johnson -- Paul E.
