A good example of the terrible, destructive effect of "upgrading" just for the sake of "modernizing" look at any of the Yahoo family of websites. They have become miserably depressing sites to try and use.
Yes - this ^
There is a great temptation to either upgrade to the latest version of a software or move to the next awesome thing BUT there is also good reason to be cautious and we are not moving anytime soon. Our forum is vBulletin and it's an older version, but it's stable and functional. A few years ago the parent company for vBulletin was sold a few years ago to a megacorp and later releases were by all accounts disasterous. You can read about the saga here: https://en.wikipedia.org/wiki/XenForo
There are a few other forum platforms out there. Currently the most promising of the bunch is Xenforo, but it's new still and rapidly evolving. We are watching...
AIR (the entire site) is actually several different pieces of software laced together. Galleries, the registry, classifieds and right side columns are each unique platforms and so making a change is complex. New for the sake of new is not a good enough reason to make a change.
