Low cost = low service
I wish that the great traveling public would realise that you only get what you pay for, that is why Ryanair is at first glance so cheap.
As some above have pointed out some times Ryanair is not the best option on cost alone and the service in very poor. In effect you are only buying the ticket to fly on the particular flight that you have booked for, If Ryanair cancel the flight they will offer you another seat but this could be days away. It is hardly a practical way to travel but it works for 99% of the pax 99% of the time and so Ryanair get away with it.
I can only stand back and admire the business skill of MOL after all he has hordes of people flocking to Ryanair to pay more for an inferior product just because of the low headline price.
