Having benefited from the Web 2.0 2010, I have had the opportunity to share what I learned plus added knowledge with others. I have had the privilege of being one of the 2 trainers in two Web 2.0 workshops held in Moi University in September and November 2012. The interaction with these two groups of trainees was to say the least amazing.
Some anonymous quote I came across somewhere rightly put it: 'If you want to keep something, give it out!' The best way to preserve the knowledge obtained from Web 2.0 training is to share it out. So, I urge all the Web 2.0 community to do three things; share, share, share.
