The document summarizes the journey of exploring different virtual learning environments (VLEs) over time in an effort to find an ideal collaborative and social learning platform called "iTopia". It discusses various VLEs tried between 2002-2010, including WebCT, OLS, Elgg, Mahara, CollectiveX, and Ning. Key lessons learned emphasized the need for a blended, collaborative approach without institutional limitations that supports an "Ubuntu" philosophy of learning as a community. The exploration is part of a larger NextEd initiative to create a global educational network based on these principles through collaboration on platforms like Ning and NextEd.info.
