For me personally one of the most important features of any webpage nowadays is one of these like-me-on-Facebook buttons. Its a real struggle to collect Likes, if people have to copy and paste a link from your *about* section. Instead a button that directly adds a like on your FB would be a great support.

Dear Ju Ko,
We have been experimenting with a social icons function for our users websites.
The feature was planned to include a new option on the site's control panel called Social.
There you would get a list of input fields for links to most popular social networks, among them Facebook.
After entering the URLs for the social profiles, an icon would be displayed in the footer section of the website.
How does this sound to you?

Sounds great, looking forward to it.
