I agree with the OP, and this comment from Christophe (@ #5) highlights the problem, to me:

"I believe there’s still an editorial oversight since, as usual, some (most?) of my suggestions got erased quite quickly, even the one I believed truly to be neat"

This person, who I'm sure has read Neatorama for a long time and knows what kind of content goes here, submitted posts he didn't even think were 'neat.' The system encourages bulk posting, increasing quantity and decreasing quality.

And yes, it clogs up my feed reader. I miss old Neatorama.
