Twitter annoyance

I understand how useful it is. It really is - especially for going out to cover stuff and being able to let the station and our web site viewers or other Twitter users know what we're covering. I like that. But I dunno if it's just me, or what, but rarely do people talk to me on it. I try to "tweet" people or start conversations but no one responds. What's the point of doing it if no one really gives a crap about what I have to say? Maybe I'm just overthinking it, or my cranky mood is showing, but jeez...haha
