When I first signed up for Twitter, I started following lots of athletes. I thought it would be interesting to see what they had to say about things. I soon found out that a lot of them tweet allmost exclusively information I don't care to devote the time to read about, including what they just ate (e.g., Jordan Hasay's pizza), where they are at every moment (airport arrivals and departures are common), and how they feel about Jesus (always positive).
If one is not careful, one can really waste an awful lot of time going through all that stuff, although I suppose if that stuff interests you, it's not a waste of time. Meanwhile, I haven't abandoned the medium because it can be a very good source of news and views about the sport. It's a relatively young medium, and I guess we all have to learn how to use it in a way that suits our interests and needs and does not burden our discretionary time.
