This one is going straight in to the echo chamber. I doubt that anyone willing to put 10+ social media icons on their blog is prepared to hear this argument. Those of us who recognize how abhorant it is have already trimmed that list down.
This disconnect stems from the difference in a core belief about design and motivation. If you believe that sharing is driven by the mere opportunity to do so, you're going to bury your blog in this stuff. If you believe that good design sells itself, you'll prioritize good design in the belief that sharing will follow naturally. This is the argument that must be made.
Although I think your point about design is very astute, I disagree with your assertion that those who need to hear this are lost cases.
I have seen some insanely huge, hover as you scroll social sharing panels on blogs of people whom I consider to be luminaries in the field of technology and design. Maybe it's a case of outsourcing the blog design or using templates just because they are there... Let's face it: slapping together a Wordpress template plus Disqus comments and some other frills then calling it 'web design' is all too common these days.
I think that getting some dialogue going on the topic is very worthwhile and I ask that people like yourself, with such astute observations on the topic not take the shoulder shrugging stance and speak out.
