Many technologies can enhance a fan's enjoyment of sports. Some others are just plain annoying. Here's five that we love and five that we're not so keen on.
When you're a sport fan, you tend to think only the best of your favourite athletes. He's a great player - must be a great guy, right? That seems true until you read the athlete's Twitter feed.
Seemingly lovable US athlete Glen 'Big Baby' Davis recently used his Twitter feed to blast the Boston Celtics for not offering him as much money as he desired, with whiny posts such as "Why is this taking so long!!! I really don't understand!!!!" and "Anybody know what's going on with the Celtics? Cause I don't!"
Former Spurs striker Darren Bent did his negotiating over Twitter when he wanted a move to Sunderland, disparaging Stoke City and Hull City in the process. And Aussie batsman Phil Hughes this summer revealed that he'd been dropped hours before the team was announced. Not clever.
Twitter can be quite useful to sports fans, offering an easy way to track the latest news without obsessively conducting web searches. But we can do without the Twitter feeds narcissistic athletes devote to their favourite topic - themselves.
