There are several Twitter integration plugins for WordPress available at the moment, one of which I created a tutorial for a while back, Publish To Twitter Automatically From Your WordPress Blog. But if you use any sort of automation program to funnel content to your blog, those plugins do not work. These plugins are only triggered when you publish a news story manually to your blog, not if you have coded your own solution to push news into a blog.
I recently set out to see how I could automate publishing news items from one of my WordPress blogs to Twitter, without any manual labour.
The solution turned out to be very easy indeed. The solution is called TwitterFeed.
TwitterFeed.com is a free tool, which automatically reads any RSS feeds you supply it, and post the number of news items you choose to your Twitter account.
The setup is extremely easy and fast, and once set up, it works very smoothly.
You can see the Twitter account which I am automatically pushing news items to here: http://twitter.com/veryfunnyvideos

I am trying to figure out how to (stay with me here). Instead of having twitter feed, feed ping.fm and than all my sites and blogs which doesn’t drive traffic to my site.
I want to have twitterfeed or (something like it) feed my site than my site feed ping.fm so The rss is coming from my site. So people habe to click through my site first than to feed they are nterested in. Is this possible?
