I have decided to implement the most common social media plugins into my website design. These being FB, Twitter, Google & LinkedIN.

I am coming to you all because I am wondering what types of placement you have used and which scenarios you deem most useful. I own a web hosting company and have implemented the links on my homepage, plan pages, organization information pages, announcements and knowledge-base articles. I have added them to my header, but did think about placing them in the footer. Please check out placement (Quality Web Hosting Solutions) and let me know what your thoughts are.

As well: For each page the plugins are on should I use my homepage as the href source or the current page url? Which would be better?
