If you offer users an amazing experience from end to end.  They will repay you with loyalty and understanding in those times where things don’t go as planned.

The only change that I am not sold on is the idea of having the categories located below the post.  To me this just makes it easier to forget to adjust/add the proper categories for each post.  For many users this information will be below the fold making it difficult to find.

One area major advancements where made in is the handling of pictures and other media types.  There is a new multi-file uploader that is simple and easy to use.  It even gives you a preview after the upload allowing you to verify that the proper files where uploaded.

If you are a current WordPress user or are considering starting a blog, I highly recommend upgrading to the newest version.
