It's not the communications, but the organising.
The organizers agree with you that organization was critical, but the means they used to form a community (organize) to mobilize was Facebook. Not only did they effectively garner support from within Egypt, they garnered international support, which limited the options for the Gov of Egypt.

IT is important, yes it just a tool, just like strategic bombers, satellite communications, nuclear weapons, submarines, etc., but it is apparent that tools can make things possible that were not previously possible.
