Abstract: Systems and methods are provided for location tracking and filtering or hiding electronic communications. In one implementation, a method is provided for location tracking for electronic communications. The method includes receiving a location ID for a location from a user who desires to follow the location within a social networking environment, and associating the location ID with the user. The method also includes providing instructions to display a representation of the location in a list of the user's contacts.

Abstract: Systems and methods are provided for filtering electronic communications. One exemplary method includes receiving a first message directed to a user, the first message including a plurality of messaging data; and receiving from the user a selection of the messaging data within the first message. The method further includes adding the selected messaging data to a database in relation to one or more contacts of the user, and receiving a second message directed to the user from at least one of the one or more contacts. The method further includes scanning the second message for the selected messaging data, and filtering, with at least one processor, the second message from delivery to the user if the second message contains the selected messaging data.

Abstract: Informing a viewer of a television program of the identity of other online identities that represent users concurrently viewing that same television program includes determining dynamically a first television program to which a television viewing device associated with a viewer is tuned and identifying one or more other viewers associated with television viewing devices that are presently tuned to the first television program. Trait information related to the viewer or to the other viewers is stored in a data store related to the first television program. A subset of the other viewers that have similar traits is determined based on the stored trait information. The viewer is graphically informed of the subset of other viewers.

Abstract: Embodiments of multicast messaging systems and methods are disclosed for facilitating the multicasting of messages and/or other content to a group of users such that users may send messages to a group. One embodiment includes a method of transmitting multicast messages, including receiving a first multicast message and an indication of a first message group from a first sending user, identifying a first set of recipients related to the first message group, and transmitting the first message to the identified recipients. Another embodiment includes a computer system configured to receive a multicast message designating a group and then to communicate the multicast message to intended recipients.
