Popular tool Ping.fm lets you distribute your content to a variety of microblogs and social networks – and it can now include your blog content to be shared automatically.
It’s a real-time feed powered by Superfeedr, which pumps out feed in XMPP or PUbsubhubbub formats. At the moment you can only list one RSS feed, but support for multiple feeds is coming in the near future for Ping’s 700,000 users.
If you’re considering the options for RSS autofeeding, Twitterfeed has been the main choice since the early days of Twitter, and also publishes to other networks including Facebook. In March they announced they have over 500,000 publishers sharing more than 1 million feeds.
The advantage of Ping.fm is that integrating the automation into your regular posting service means you’re perhaps more likely to keep it updated and compliment it with non-automated posts, whereas Twitterfeed can encourage a ‘fire and forget’ mentality, where your RSS feed becomes your entire Twitter stream. One solution to this is to create specific identities for your RSS streams. For instance, I tweet at @badgergravling, but also have @thewayoftheweb, @140char_com and @onlinedriver for each of my sites (Please feel free to follow all of them!)
