Doesn't mean that there aren't a lot of GREAT films from each of the listed directors. Google, Wikipedia and Netflix are your friends.
On a more serious note, whether someone agrees with those choices or not as being "snubs", wouldn't hurt to at least be familiar with the careers of each of the directors I listed. Maybe at least some of them will strike some interest with some members, and if so, then it made making the post worth it to me.
That is all.
