Tunisia: Will there be a domino effect?

There is speculation about a possible domino effect similar to the collapse of Communist governments around Eastern Europe in 1989.
In several countries of the Middle East and North Africa, youthful and rapidly growing populations face rising food prices, high unemployment and lack of political representation.

Mauritania, Algeria, Egypt... distressed men set themselves yesterday and today on fire to protest their situation, copycats of what seems to be the ignition of the Tunisian crisis when a young man committed suicide following his difficult economic situation.
