Glow blogs were upgraded to WordPress 4
Moving to WordPress 4 was a major upgrade. Moving from version 2.9.2 to 4 of any software will bring changes. Among the major changes are:
An improved menu system, making creation of more complex navigation, you can find a tutorial on menus: Creating a Custom Menu in WordPress – WordPress 101 Tutorials
Much better media handling, WordPress displays media natively without the need for plugins.
Much improved mobile interfaces, see: #glowblogs improvements: mobile – John’s World Wide Wall Display

A generally better editing experience on modern browsers.
The WordPress Admin Bar a shortcut area that allows you to access the blog controls when you’re on the front-end of your WordPress blog or website. (you can turn this off in your profile) Here is a good tutorial:Using the WordPress Admin Bar
and most importantly a way to move forward and add more features in the future.
We have several new themes and some existing themes have been updated too.
While it might take users a short time to get used to the changes, we think that this will be a very positive upgrade to the Blogs service.
The Help blog will be updated to support WordPress 4 over the next few days.
