Self fulfilling Truth:

It is easier to criticise...

Requiring only the power of observation and the willingness to voice an opinion a Critic, endowed with the inalienable right of free speech, can offer any criticism he/she likes.

Claiming the 'aire' of contribution the Critic is a follower. Offering "helpful insights" and "constructive criticism" the Critic enjoys a lofty position of objectivity and intellectual distance. The Critic seldom if ever contributes before the fact. Seldom if ever leads. Seldom takes the risks of inovation and discovery. The Critic just sits in a comfortable space and passes judgement.

That is just my $0.02
