Abstract: An embodiment of a system and method of surveying users on a social networking system is described which limits the frequency in which any one user is surveyed. Users are assigned into a multi-layered survey pool based on a hash value derived from a user identification number for the online social network that is assigned to the user. Users are randomly offered the opportunity to take a survey, and the subject matter of the survey is at least partially determined by the layer from which the survey obtains its sample populace.

Abstract: Techniques to rate-adjust data usage on mobile devices using a virtual private network are described. In one embodiment, an apparatus may include a processor circuit, and an application component operative on the processor circuit to present a link to third party data, receive a control directive to follow the link, and to request to access the third party data. The apparatus may also include a client virtual private network (VPN) component operative on the processor circuit to communicate with a server having a server VPN component, receive the request to access the third party data from the application component, determine whether the accessing is rate-adjusted, and connect to a source of the third party data via the server VPN component. Other embodiments are described and claimed.
