    Have a read of this article: http://www.behind-the-enemy-lines.com/2012/04/feedback-unemp... There's good reasons to believe that the portfolio that designers develop through 99designs is likely to be worth far more to them than the win itself.

  21. I'm glad someone else is calling this for what it is: a way to get around minimum wage. Another solution would be to use worker reputation (something explored by Panos Ipeirotis @ http://www.behind-the-enemy-lines.com/ ) Because MT workers are unreliable, you often need to have several doing the same task. Better workers require fewer checks, and are therefore much more cost effective. Right now MT is a market for l…

  23. > What kind of AWS setup leads to surprise bills? You only need a single configuration wrong to get bankrupt overnight, and AWS has so many knobs that make a switchboard look like a toy. I remember things like [1]. It’s very easy for something you don’t control go rogue, and AWS offers no protection for such scenarios. 1: https://www.behind-the-enemy-lines.com/2012/04/google-attack...

  29. Humans being the error-prone creatures we are, I wonder how it could work better to a longer word-based code, but allow for certain kinds of errors: for example, 1) word order doesn't matter, 2) it tries to correct a word not in the built-in word list to the "closest" word in it, 3) maybe you only need, say, seven of the eight words to be right to get in (then it might remind you of the real code). You can do a litt…
