Rather than actual critique, here is a user story. It takes place...
inside my brain!diiq's story:
----------
Will there be 250 credits worth of content soon? 5-10 credits a video (maybe), 2-3 videos per month (maybe), that's... nearly two years, if the videos are cheap?
Trying buying credits. Why can I only by credits in these numbers -- why not any number? Some of the screencasts cost 8 credits. I don't want to pay 10 dollars for what you say is only worth 8.
Ohhh! I'm supposed to go somewhere else to redeem the coupon... hunting for the right button.
Found it. Aaand the coupon doesn't work. Hmmm.
So I guess I'll download a preview. Maybe it'll be worth $10 to see more. I'm pretty good with PHP, and I've done TDD, so I'll grab the iPhone development masterclass --- I don't know anything about iPhone development. Maybe I'll learn something. Downloading... wondering why this isn't embedded...
Watching a splash screen and music...
Hmm. Something about a method that gets the number of lines. Whoops! Preview is over.
I should get back to debugging.
---------
It's not a story with very happy ending, I'm afraid.
