Ever wish you could post to all of your social networks at one time? Enter Ping.fm.
Ping.fm is a free service that allows you to post updates across all of your social media networks simultaneously. Since not every post is appropriate for every network, you can pick-and-choose what to send and where.
Ping is diligent about adding increased functionality and features to the site (especially in the mobile application arena), which is nice to know, as the technologies seem to literally evolve weekly.
