I am running my own blog using wordpress, last day i installed seo by yoast plugin, which inserted meta tags on my site to enable twitter card on my tweets. i disabled plugin but my tweets still showing url preview in tweets, here is screenshot: http://screencast.com/t/lBaJN7t1qzj
here is my site url: http://empirereportnewyork.com/
here is my twitter acc: EMPIREREPORTNY
Pls help me to remove this preview, as i have to tweet very often, its annoying for people to see my site’s preview every time.
Thanks in advance,
