A commenter pointed out that DuVin Osteria, the new spot coming to 1401 Florida Avenue NW, is the same one that was the subject of a controversy last week -- blogger U Street Girl posted about the new place, and then a commenter on her blog posted something negative about the owner, David Shott. Shott then emailed U Street Girl and threatened to sue her. She then removed the comment.
DCist points out that Shott has no legal ground to sue under the Communications Decency Act, which says that blog owners are not liable for things commenters say.
It looks like Du Vin has since deleted their Facebook page after the bad publicity, as the story got spread around. Even Yelp has negative reviews already.
Maybe not the best way to introduce your establishment to the neighborhood.
