Blogger has a Beta site where users can experiment with new features being considered for inclusion in future releases. I have been playing with the site so, some of the new features you see here might be temporary.
Two of the beta features I like best are the ability to add any Google Webmaster Tools to the side bar and the ability to schedule a post for a future date and/or time. The METAR box, the blog roll and the new search box are examples of Google Gadgets.
Look for new features to come and go as I explore more capabilities and try some of the gadgets. If you see something you especially like or dislike, let me know. I value your input.
