Here is a collection of some of the most popular Social Media platform icons that we created using http://fontawesome.io/
You can download these icons and use them for whatever you please. They are .png files and each icon is 32px. These icons are using the colours from the Shift8 Web brand, but you can adjust the colours in Adobe Fireworks to whatever you wish.
In this case the icons are images, but if you are interested in using Font Awesome icon set on your wordpress website or blog, you can do this really easily using a really simple plugin: https://wordpress.org/plugins/font-awesome/
The plugin will allow you to use all 361 Font Awesome icons, there is a lot of documentation that you can read through on the plugin download page.
