When people asked me for the URL of my blog they sometimes asked how to create the link. I created a links page and wrote:
To link to my journal:
(a href = "http://firemind2.blogspot.com")Firemind(/a) - replace the () with <>.
I then went on to explain how to link to individual posts.
I did it this way because it worked and I didn't know how to display html code in a post.
I have come across several posts showing how to display code in a post. The latest being 'Displaying code inside a post' at Beautiful Beta. A reader (Shelly) left a comment there that led me to Quick Escape - a tool which turns the html into postable characters.
Now I can show examples like this:

Blogger makes it very easy to create sidebar links now. We don't have to paste the code into the templates but just add the URL to a link list widget.

The code will create a clickable button like this:
