No it isn't. Because it adds a certain degree of difficulty to the game, and it keeps it fun. Anyone can type a coaster name that starts with the right letter. But to actually sit there and think "Okay, what coasters start with _ letter?? Okay, now have I been on any?? YES!! YAY!! I CAN POST!!" IMO it makes the game better.
Anywhore,
