Well this is a tuffy. We’d have to start by defining change and how that change can be measured, etc.
I know I have broadened certain outlooks based on some of the contents here and that of course results in some sort of change inside and outside this site. I find I am forced to constantly review my views and a lot of times I have to reconsider them in light of other people’s points of view. That in itself is learning and learning is broadly defined as acquiring new or modifying existing knowledge, behaviors, skills, values, or preferences and may involve synthesizing different types of information.
In general terms, I have also confirmed some of my views about human nature regardless of where people come from, here you can observe some of the same behaviors as in real life. To be quiet honest, in a way my expectations of this forum were higher, but I sadly find a lot of people who are clicky, territorial, deffensive, touchy, rude, one sided, superficial, reluctant to understand, lurve starving, etc. But then again, most are always ready to help and share what they know, and that’s a great thing.
