When massive number of people are doing something, my advice is to do something totally different. For example, should I do iPad games because everybody else is doing them as well?
What “everybody else” is doing, doesn’t really matter for me.
If Cliff does something, it’s good to take notes, and consider if you can lend some of his knowledge & experience.
I’m sure he won’t mind.
In case you don’t know who Cliff is, well, his GSB game has got over 100000 people playing it. The game costs about $20 to buy, so do the math.
