The Website of UX Designer Matthew Stephens

Mashable has put together a great list of the best features. Here is a quick summary:

1. Custom Post Types – Finally, I can update my portfolio without hacking WordPress. This will be huge for people who manage content within pages.
2. Menu Management – My favorite feature of 3.0, since I am constantly using widgets to hack sites’ menu navs.
3. Custom Taxonomies – This feature makes WordPress much more of a “genuine” CMS. Great for tracking fields of data.
4. New Default Theme – Finally, a good theme that doesn’t need to be immediately replaced on fresh installs.
5. Multi-site Support - This will be great for my corporate clients running WordPress who want to allow one editor to maintain many sites at once. Very convenient.
6. URL Shortener – So long bit.ly.
7. No more automatic password generation – That was so annoying.
