I think it’s boring to post updates in your blogs to social networks manually.
Octopress by deafult creates atom feed available on sitename.blah/atom.xml
I’ve googled a bit and it looks like no social networks support direct posting from a feed and this is weird. Let’s see what can be done with this.
So I’ve registered on Twitter and service Ifttt which allows to channel Atom feed to Twitter.
Then in Twitter profile settings I’ve connected it to Facebook and in VK settings I’ve connected it to Twitter.
Hope it will work. If so this will be my first blog post shared via social networks.
There is no such option for Google+ as far as I know, maybe I’ll manage how to connect blog to my profile but not now.
