Elliott,
Here's an example:
http://www.rebarcampsa.com/2011/08/rebarcamp-san-antonio-beginnings/
At the end of the post I have used shortcodes to generate the Facebook, Twitter, and Google+ links.
For each post, this means three shortcodes to generate that group of sharing icons/links. I'd like to create a widget that holds all three of those, so that I can use a widget shortcode to insert that into each post.
Here's the current shortcodes:
[fblike layout="standard" show_faces="false" action="recommend" colorscheme="light"]
[tweet username="REbarcampSA" layout="horizontal" text="How REbarcamp San Antonio came to be. #REBCSA"][googleplusone size="small"]
In addition, when you click on the Tweet link, it generates a pre-filled tweet with pre-defined information (that I supply in the shortcode with the "text" option). In the case of this post it's "How REbarcamp San Antonio came to be. #REBCSA"
I'd like to be able to generate the text option using Wordpress' %postname% variable or another variable (I'm not sure what the variable is for titles, but that would be the best one).
By doing this, I could create a widget that would place all three social icons/links at the bottom of the page, plus pull the post title from Wordpress and place that in the text option.
Does that make a bit more sense?
