Since Facebook, Google+ and Twitter also transmit data when the button is not clicked at all, these services are now integrated via a 2-click solution originally conceived by Heise.de. According to data protection experts, this integration is not optimal either, but it is a step in the right direction. It also means that the speed of the site does not suffer, and all the options for sharing contributions can be accessed with two clicks.
More information about this solution can be found at Heise.com. This solution is already used on several websites, the number will hopefully increase (of course, the best would be an automatically correct working solution of the respective social networks, although such a thing is hardly to be expected).
