If you're posting company news, especially personnel issues, there has to be an official, published source, and it's best if you include the link in your post.
- Press releases
- Company web site
- Newspaper article.
- Verbal conversations, no matter how reliable the source. The only exception to this rule is if a company official states or announces something in a public Q&A. Alexei Ratmansky coming out and promoting a dancer in a curtain speech would be reportable, but your conversation with the dancer, even if it's the dancer involved isn't.
- Blogs, except for company blogs and professionally sourced blogs. Unless the blog has a quasi-official status, assume that it isn't kosher - or ask us.
