I remember asking Guy about this AMA Reddit thing, actually there's nothing to be "ashamed" of in it. I mean Michael Stevens of Vsauce did it, Stephen Hawking did it. I can end it there, but anyway it's one of the greatest things of interaction between fans and "artists". I mean Stephen Hawking couldn't even write the answers himself, but somehow managed to do it, and Mark seemingly can only answer one question: How you started on guitar? Anyway, this is an old rant about an old-school guy which never would lead to something rational. Long story short — it's Mark.
