There are quite a few things that need to be enhanced on the social buttons and social features in Marketo just to make them usable, specifically for European or Asian companies whose social network priorities are not limited to the usual suspects (Twitter, LinkedIn and Facebook).
See this idea for instance : custom social buttons
Things such as customizing/suppressing the "Marketo Social would like to access your data" message that repel almost any visitor. We have done some A/B testing with Marketo buttons and standard non Marketo buttons and we end up with 5 to 20 more frequent sharing with the non-marketo buttons. The marketo social buttons share rate is 0.04%!
