Sitepoint’s main audience are programmers, designers, etc.
We programmers/designers have change embedded in our DNA. We accept change more easily because our livelihood requires it. We need to evolve to continue to grow.
That doesn’t mean that we will not complain when our favorite site changes. It does mean that we adapt and accept change at a faster rate compared to any other group.
Another reason for a group to accept change more easily is that they are “programmed” to accept change. I do this by constantly making changes to the site. The members now expect it.
I remember the first time I did a major upgrade to the site. (I just came on board.) We had a major backlash. Not as bad as Digg but it was ugly. Since that day, changes on the site are on a yearly basis. Now, members are more acceptable to change … they understand why change is important and offer valuable input more rapidly.
