RSS reader with "tweet this article"

[Koovin]

So I just switched to the iPhone after almost a year and a half of having a blackberry. One of the most addicting apps I had was Viigo, an rss reader that gave me the option of tweeting an article I want to share. Is there any iPhone app out there that has the same feature?

I've tried most of the RSS readers and none that I know of have this functionality.
