Abstract: Discussion of content between users of social networks is described. A request from a first user to discuss content with a recipient user in a first social network is received, wherein the recipient user has a first identifier in the first social network. A request from a second user to discuss content with the recipient user in a second social network is received, wherein the recipient user has a second identifier in the second social network. A discussion is initiated between the second user and the recipient user about the content in the second social network. The recipient user is tracked in view of the first identifier in the first social network and the second identifier in the second social network.

Abstract: Embodiments of the present invention provide an automated scheme for identifying high/low value content. Playback data from users in a social network may be periodically submitted by users of the social network. The playback data indicates segments of content, such as audio or video that the user has skipped over or tagged as low value. The playback data may also indicate segments of content that the user has repeated or tagged as high value. The playback data is then analyzed in aggregate and various clips are identified. In addition, the playback data may be compiled and organized among the users for future use. The playback data may be used to indicate segments of high/low interest to peers in the social network or to arbitrary users.

Abstract: Embodiments of the present invention provide a mechanism for automatically creating a playlist for a user.

Music is then selected from this data and gathered from a music service in which the user subscribes, such as iTunes, Yahoo Music, etc. The service then builds the playlist with the gathered music.

Abstract: Provided are systems and methods for separating a purge gas recovered from a polyethylene product. The method includes recovering a polyethylene product containing one or more volatile hydrocarbons from a polymerization reactor and contacting the polyethylene product with a purge gas to remove at least a portion of the volatile hydrocarbons to produce a polymer product having a reduced concentration of volatile hydrocarbons and a purge gas product enriched in volatile hydrocarbons. The purge gas product is compressed to a pressure of 2,500 kPaa to 10,000 kPaa, and is then cooled and separated into at least a first product, a second product, and a third product. A portion of one or more of the first, second, or third products is then recycled as a purge gas, to the polymerization reactor, or to the purge gas product enriched in volatile hydrocarbons prior to compression, respectively.

Abstract: Embodiments of the present invention provide methods and systems that allow users to share information about their recent activities with other users. In particular, as users receive and/or share multimedia content with other users, information that indicates the locations of this content, such as a website, playlist, or file, is passively tracked and logged. This information may be formatted into a viewable form, such as a web site or web log, and cooperatively shared with other users. Users may then incorporate the multimedia content played by other users into their own library. Users may also elect to synchronize their multimedia content with other users. For convenience, multiple locations for the same multimedia content may be determined when it is logged and tracked. Users may obtain the multimedia content using one or more of their existing accounts with a provider at their own discretion.
