This is because it’s the ‘Default’ category in WordPress. So, if you forget to add a category to your post, it’s going to be put in the Uncategorized category. If categories are displayed with your posts or in your list of categories, it looks kind of lame.
Since version 2.9 WordPress has supported Post Thumbnails, which are used to assign an image to a post so they can be used in different parts of the theme and are frequently used in magazine style layouts. Prior to post thumbnails, custom fields were frequently used to do this.
I used to use the Thumbnails for Excerpts plugin to improve the layout of my search results page and my archives. For some time I’ve wanted to use Post Thumnails instead but the thought of adding them to all of my older posts seemed like a daunting task.
I am frequently asked how to make a custom Facebook tab the default landing tab and realized that I haven’t written this up before. And, the location to do this has recently changed, so if I had written an article before, it would need to be revised. You do know that when writing about Facebook, it really should be done in pencil. ;-)
WordPress 2.7 comes with an auto-upgrade feature, which makes upgrading much easier but is not without it’s potential problems. So far, I have come across three issues that seem to be the ones most frequently encountered.
The three issues are related to losing theme customizations, the upgrade won’t occur because of a plugin incompatibility, and lack of core support from your webhost.
