“Wikipedia” -> “Google Knol” -> “Academic Earth”

I had been a heavy duty user of wikipedia for quite some time.  It empowered a whole new generation of knowledge seekers by using the power of internet communities to enable knowledge transmission. Slowly I feel Google’s knol is entering into Wikipedia’s turf. Another interesting contender which recently entered the fray is “Academic Earth“. Although the coverage of topics might not be that exhaustive as in Wikipedia or Knol, it scores over the wikipedia and knol in terms of authenticity, coming from the real classrooms of Yale, Harvard, Stanford etc. Will be interesting to see how this initiative unfolds into the future.
