Doing what you believe is right or doing the thing that will be popular are markedly different.
For a start, the popular thing has already been done many times, that's why it's popular.
And popular ideas are only popular until the new popular thing comes along.
And that's now, popularly, about every five minutes.
Unpopular ideas touch a nerve, they are controversial, go against the grain, they zag.
In fact, unpopularity of an idea is often directly proportionate to it's interestingness.
The problem with doing what's popular, is that nearly everyone else is doing it too.
As it's Friday have an Oscar Wilde diptych for your powerpoints:
'Popularity is the one insult I have never suffered...
...to be popular one must be a mediocrity.'
