Blogger provides us with a native accessory, called a "Blog Feed" gadget, which will provide acceptable "Recent Comments" and "Recent Posts" functionality, for many blog owners.
Look at the sidebar of this blog, for "The Real Blogger Status - Comments", and "The Real Blogger Status - Posts". Those are "Recent Comments" and "Recent Posts" gadgets, based on the Blogger supplied "Feed" gadget - which is not a third party accessory, and is not subject to future third party peccadilloes.
To make your new gadget, start with the URL of the blog feed desired. Then, add a Blogger supplied Feed gadget, using the "Add a gadget" wizard, in the dashboard Layout display.
This is the URL of this blog.
This is the URL of the blog comments feed.
This is the URL of the blog posts feed.
Setting up a "Blog Feed" gadget is simple enough.
- Add a "Feed" gadget (Only select the "Feed" gadget, "By Blogger"!!!), using the "Add a gadget" wizard. Avoid any similarly named gadget not "By Blogger".
- Plug in the Feed URL (see my examples above), and Continue.
- Review / change the options offered, and Save.
- Test your new blog accessory - provided by Blogger - with no future hacking activity anticipated.
And, you're done. Wasn't that simple?
