I'm making a website that you can upload images to. Implementing social network sharing buttons for content is turning out to be a pain and not to my liking in that it requires extraneous Javascript to be introduced and negatively affects the aesthetic (obviously some agree with me, as the Ghostery browser extension has an option to remove them from any webpages visited), so I'm wondering if they are an absolute must if I want to get some good traffic.
I noticed that they are on most every site (including sites that contain things that most people under no circumstances would want to share on any social network), and even then there is no real standardized button set - every site typically has a Facebook and Twitter button, but some offer Pinterest, Google+, Tumblr, etc. variably.
Do people really use these buttons or do most just copy paste the link into their sharing platform of choice? I'm not a social network user so I am unsure myself.
