Are item levels and stats increasing too fast?

Blizzard recently released a blog post that addresses the exponential growth of stats. Multiple tiers per expansion combined with a desire to make the leveling process in an expantion require gear replacement has led to stats that are quickly reaching levels that make gear look a little absurd.

It's an interesting look at how blizzard is trying to deal with this problem.  ZAM user IDBrownFish has started a thread on the topic.  Drop by and add your thoughts.
