Although Twitter has the facility for direct or private messaging, that is not the point of Twitter
It is really for broadcasting a message, or specifically information to a wide audience. The message must be brief, but it can include a link to more details
Someone might feel the need to get a message out there, but many just post crap for the sake of it
But for getting information direct from people or organisations that interest you, you wont beat it.
As an example, I can get almost instant details of motorway hold ups - a brief location and a link to a live map showing more detail. Or messages about discounts etc from merchants, or latest legal rulings, or what the Police helicopter was doing over my house at 3 AM
Just subscribe to the people or organisations that interest you - you don't need to post anything
