It wasn't meant to be taken seriously. It isn't that big of a deal really. You're right.
It's just funny.
It's more like you're frustrated because the game you want to buy with the money you have is not coming up as a sale fast enough to satisfy your desires.
So what if TWD came up 3 times (a flash deal, a community vote and a daily deal)? If The Witcher 2 came on the first day, you bought it and that was it, would you care as much about TWD getting 3 chances to be sold?
Everybody complaining sounds like "omg the games I want for the prices I want are not coming up, this sale is horrible. Screw everybody else" to me.
When "Mark of the NInja" came up as flash deal, everybody was expecting that. Suddenly, it was an amazing deal, Steam Sales redeemed, etc etc.
Except the game was only 50% off. Technically, that's a bad discount. But everybody was hella excited, because everybody wanted the game no matter what the price, they just wanted a discount. When it comes back as a Daily Deal, people will complain again.
And when it's 75% on the summer sale next year, people will complain again.
If the sale ends and the game you want doesn't come up for the price you want (for instance, Dead Rising 2 in every sale except this one), then you're more than correct in complaining.
