The launch of Google's OpenSocial platform earlier this month might have been more PR than anything, as many of the third-party partners implementing the new developer standard won't be releasing anything for months.
Instead, OpenSocial-related announcements have been rolling out slowly: one of the latest is that social music site Last.fm has created OpenSocial widgets designed for use on Ning, a site that allows any person or business to create a specialized social network. (According to Ning, more than 123,000 networks have been created so far.)
Ning network creators and members can now install the Last.fm music application into Ning pages. It can display the top artists they've listened to, songs they've played recently, a custom list, or a player to hear recommended music.
