In the spirit of "Pay it Forward", I had previously introduced a bunch of friends to Kubuntu Linux, and they have embraced it completely - so much so, that they have begun passing Kubuntu along to other friends and colleagues of theirs.
This is a great example of how well Kubuntu works today, and what a few people with some initiative can accomplish. Imagine if each person who switched to Linux was able to get one friend or collegue to try it out and they in turn make the switch.
Realistically, this probably won't happen, but if just one in 10 people you introduce it to was able to convert someone, the numbers would begin to add up. Even my Mom is proudly telling everyone she uses Kubuntu, and surely that's a testament to the power of Linux today.
