Nice to see a presence, but half a dozen accounts and not one that focuses on major news headlines? Aa it stands the unofficial bot that reposts from the Twitter account will still get more interaction from me.
tennis@sports.bbc, italy@foreignaffairs.bbc, you name it. They can implement combination feeds by making sports@news.bbc boost all the individual categories, so people can easily find the specific types of news they're interested in.
In the end I think they'll keep down the variety, sticking to a Twitter like experience.
