"We're sorry, twitterfeed is currently unavailable while we're working on fixing a hardware-related issue."
You can read twitterfeed.wordpress.com or you can follow @twfeed to know the update about twitterfeed status.
We were automatically sending tweets from RSS feed to @globaltechnews using the twitterfeed only.
I wanted to avoid any interruption in our news delivery.
So, I searched other options for handling this issue.
While searching for other options, I came to know that Google Feedburner is itself providing this tweeting service.
We can easily use this by following below steps.
Click publicize->socialize in your feedburner web page.
And then add your twitter account.
Google will use goo.gl for shortening the url in the tweets.
You can refer the sample tweet from the Google feedburner.
But I am not sure about at what frequency Google will post the tweets from the feed.
If anybody knows about it, you can share it thro' the comment section.
And, it seems some other alternatives are also available.
