One of the confusing things about the Google Blogger interface is the little pencil and the little criss-cross tools (screwdriver and wrench) icons on your page as you view it. They are short-cuts and they are only visible to you, the person who is logged in to your blog. They don't show up for anyone else.
The pencil tool icon allows you to go directly to edit a post. The criss-cross tools icon allows you to go directly to edit a gadget. It's actually pretty cool.
Just wanted you to know. Now go blog!
