PING
                Ping is social networking specifically for music. With it, music lovers can follow artists, see their videos and photos, view tour dates, and see what music the musicians are listening to. On Ping, users create a profile that allows their friends to see everything about who they are following, what they are listening to, and what concerts they intend to attend. The Ping equivalent of a Facebook Newsfeed shows posts from artists and friends about artists, albums, songs, and concerts they do (or don't) like. Along with the feed, Ping users have access to a Top 10 list--a list of songs and albums their friends and followed artists are downloading. To make it all easier than it already sounds to the social media-savvy teens of today, Ping users can comment on artists, albums, and songs straight from their library.

Oh, and to calm everyone who feels Facebook is enough of a privacy invasion: Ping can be disabled.

BING
               Bing was advertised to be not just a search engine, but a decision engine set to help you choose anything from where you eat dinner to who you date. A helpful feature Bing offers is a sidebar full of different options to refine searches and give you better results than Google can offer. Like Google, Bing has a bare and easy to use home page--just click the search bar and start typing! 
Many Bing users say their results were less accurate than those of Google or Yahoo and, chances are, they are right considering eight out of eight people surveyed preferred Google. However, Bing is constantly being modified to become better than its predecessors 'MSN Search,' 'Windows Live Search,' and 'Live Search' and so far it has been working. To make life even easier, Bing can display sports stats, stocks and quotes information, solutions to complex math calculations, and even spell check all from the search page--no linking necessary.
