Ping.fm

Ping.fm was an advertising-supported social networking and micro-blogging web service that enabled users to post to multiple social networks simultaneously.
Making an update on Ping.fm pushed the update to a number of different social websites at once. This allowed individuals using multiple social networks to update their status only once, without having to update it in all their social media individually. Ping.fm grouped services into three categories – status updates, blogs, and micro-blogs – and updates could be sent to each group separately.
Ping.fm was shut down on 5 July 2012, to be replaced by Seesmic Ping. Seesmic was later acquired by HootSuite.
History.
