>And then Twitter is used for "relevant" information as well, from emergency or transport authorities using it for quick information instead of having their own system to news of any kind or discussions and information exchange in different peer groups.

I really don't think it's wise to be putting so many eggs in one basket, convenient as that might be. This right here is a strong example of that.

Of course using Twitter as only/primary channel is and always was questionable, but alternative systems are more expensive.
