Forum:Using official twitter pages as a source?

i was reading the manual of style recently and was wondering if tweets from official accounts such as https://twitter.com/#!/bbcdoctorwho and https://twitter.com/#!/steven_moffat count as valid sources for articles on this wiki. it didn't mention anything in the manual of style about that sort of thing and if it is allowed, can i suggest it be added in.
