Video produced by Ross Chapman -- The second Tuesday of each month, social changemakers and web innovators get together to network, socialize and share ideas at Net Tuesday, an event produced by NetSquared a project of TechSoup. This month we have three speakers: Adam Frey, Co-Founder of Wikispaces, will talk about his company's work, and how nonprofits and educators can use wikis. Rushton Hurley, Director of the nonprofit, Next Vista for Learning, and Greg Wolff, President of the nonprofit, the UnaMesa Association, will talk about how they use wikis for their work. Speaker Bios: Adam Frey (pictured above) is a Co-Founder of Wikispaces, a provider of easy to use and easy to adopt hosted wikis. Wikispaces provides public and private wikis for small groups, and private label wiki environments for organizations such as schools and nonprofits. Prior to founding Wikispaces, Mr. Frey founded and managed the SourceForge line of business at VA Linux Systems (later VA Software). Frey holds a Bachelor of Science degree with Honors from Monash University and an MBA from Columbia Business School. Rushton Hurley is the Director of Next Vista for Learning, an education-focused 501(c)(3) nonprofit that is building a free, screened library of video content by and for teachers and students everywhere. Hurley has taught at the high school and college level, been a school principal, worked with charter and traditional schools, and organized and run an online school. His graduate school background at Stanford includes exploring technology-enhanced learning through multi-media and speech recognition. The idea of helping students become more engaged in, and confident with their learning is one that drives his passion and resources to make this project succeed. Give him a few minutes, and he'll convince you, too. Greg Wolff is the President of the UnaMesa Association, a public charity dedicated to improving health care, education, and social services by supporting the individuals and small teams who provide these services. UnaMesa acts as an R&D organization with projects that bring together industry, academia, and NGOs to develop and distribute effective tools. Wolff has over 15 years in the research, design, and development of systems that support collaboration within and between work groups. He was a 2004-2005 Fellow in the Digital Vision Program at Stanford University, and is currently Vice President of Ricoh Innovations.
