Reading a fact box online or a 'Quick Guide to ...' in the paper has given those with little or no real understanding of each sport the opportunity to share their 'expertise' with anyone who'll listen.
The London Olympics have been dubbed the first "social media Games" with sports fans and athletes heavy users of Facebook, Twitter and the video-sharing site YouTube to talk about events as they happen.
Interestingly, it turns out we use up less calories sitting down and watching TV than we do when sleeping in bed. So while the interest in sport is a good thing we may not be taking enough advantage of the possible impact of exercise on our own health as we think as actually being asleep is better for losing weight. And, to be honest, those snacks while watching sports on TV probably aren't doing us any favours either.
But surely it's a good thing to get us watching sports, especially those sports you would never have considered before, when it might lead to us considering a more active lifestyle?
The growth in levels of obesity in developed nations has slowed down over the past decade, but there are still more obese people than ever before, according to a study earlier this year by the OECD (Organisation for Economic Co-operation and Development).
In 1948, the so-called 'Austerity Olympics' in London had this Olympic motto:
"The important thing in the Olympic Games is not winning but taking part. The essential thing in life is not conquering, but fighting well."
Leaving aside the comment about conquering and fighting being used just after WWII, the motto would make you think that sports are not competitive. That winning a medal is not a vital reason to do your best.
The London 2012 Olympic motto is 'inspire a generation' which is why any involvement in sports for spectators seems like a good idea, even if it is tweeting their new found knowledge on a niche sport. While basketball may well be one of the top sports in the US, it's not played in schools in the UK yet kids are now begging to go and "shoot some hoops" so it's getting us outside and off the sofa and surely that's a good thing?
