I disagree.
I’ve been though the Steam Sales for well over 10 years now, and I remember when they switched up how they did it.
Yeah you no longer have a 90% discount for a single day on a game so there isn’t anywhere near as much chatter, which I miss, but there are plently of big names with 90% off. I think that is either what you miss, or you are now 5 years older and just don’t get as excited, or there hasn’t been much released that interest you.
Games with good reviews and 90% off:

Is it the sales, or are there just less games coming out at the moment that interest you at any price?
Here are some other examples:
A book, The Cathedral and the Bazaar about software development.

A fashion and “lifestyle” magazine

We have a lot of foreign food stores around here that are called “The Bazaar Supermarket” etc.
