We keep developing new tools to get a better conversion and interactions with social networks in your page.
We introduce the CTA feature. When the page is near end, a box y displayed to share the information. This is called "CTA" or Call to action, and it is very effective because you want to share once you end to read. CTA offers you a push to share.
Another thing we develop to be include in the Social 2s plugin is the support for twitter cards.
We have some ideas and we are at this moment researching to develop the fastest and most customizable social plugin for joomla!
