A few years a go I registered the domain richtweets.com and coded the the app during a weekend. On richtweets.com you create a page and post the link and some characters on Twitter, using the Twitter API.<p>I did no marketing, but the site got some traction and has now about 50K visits monthly. (https://twitter.com/#!/search/realtime/richtweets.com)<p>I used Adsense, to monetize the site, but Google deactivated Adsense on richtweets.com today and this is the reason http://support.google.com/webmasters/bin/answer.py?hl=en&answer=66361
It is actually like a blogging service like blogger.com or wordpress.com So if you want to post more than 140 chars on Twitter, you can login with your twitter account and publish your text, photos or videos.<p>Google is not right. The site has a lot of original content. Even Brazilian government authorities use richtweets.com to talk to their people. We have over 20k posts an these posts get a lot of comments, retweets and Facebook shares.
