You're turning a factual story into fake news. >but how many are actually doing it? A lot? A few? No one knows except Google and fitbit. As it is, is exactly "some"and since a lot of fitbit owners don't tweet, precisely because they care about privacy, the actual number is almost definitely a multiple of the tweeters. What word other than "some" should they have used?
