Our post might be pinned because we laid out in more detail than most what we are trying to accomplish. It's part PR for other K-12 districts (which we actively seek to convert to Moodle) and part sharing to inspire others. Whether we are from the US or elsewhere it is a very compelling success story that includes both the software and reasoning behind it.
My personal fear is there is much more traction for Moodle happening in the EU and Spanish speaking areas. This might cause Moodle to devote more resources there and less in the US where there is more competition.
I would hope that others would share like we have in how they built learning communities/platforms using Moodle. It's the exchange of ideas that creates synergy and new ways of doing things to help students. Much more powerful than the tools we use are the ideas, methods, and implementation that I also attempted to highlight in that discussion. We are playing the long-game. We've been at this for some time and have no plans to change course with our support and involvement in open source educational projects.
As for Google... much like Microsoft there is always a tradeoff both ethical and financial. We can purchase 2 or 3 Chromebooks for the cost of a single laptop or iPad. Unlike a tuition-based college, the math adds up quickly with a limited K-12 budget that is smaller and smaller in the US every year. We pinch pennies. Providing technology for 22,000 students is no easy feat. Managing devices for 22,000 students is no easy feat. Google has the best management tools Chromebooks and their office suite is ideal for sharing and collaboration. We can deploy our lockdown browser App to 17,000 chromebooks in minutes from a web interface. That doesn't exist in open source very easily or as integrated as it does with Google's products. Sometimes you have to make compromises and each organization has to weigh the pros and cons of Google Ed or MS 360 and how much student data is shared in order to successfully educate students. We don't have the manpower or hours in the day to develop our own management and backend infrastructure to compete with the out-the-box solutions from Google or Microsoft.
Today it is Google. Tomorrow it might be the company from the kid tinkering in their garage.
It's our job to give that kid in the garage the tools and skills to pursue his/her dream to the fullest.
