That simply isn't true.
People may not want to watch 5 days of cricket, but it is simply incorrect that they do not have the time. Does time flow faster in 2009 than it did 10, 15 or 20 years ago? Is the day only 20 hours long now? Does time flow a a different rate if you are 20 years old than if you are 40 years old? No it does not. People who don't really like Test cricket simply do not want to make time, if you like it you will make the time. Plain and simple fact here is that it doesn't really matter what you do to Test cricket, hold it at night, have topless women handing out free beer, if 5 days of cricket is not for you, it won't be for you if it's on at a slightly later time in the day.
As for a draw being confusing, thats rubbish too. Sure some tests are pretty even and don't look like they would yield a result if you kept playing past 5 days but anyone who understands cricket even a little bit can decide who they think had the upper hand throughout the twists and turns of the match, they don't need a scoreboard telling them.
