The new "needs more focus" wording is
Needs more focus
This question currently includes multiple questions in one. It should focus on one problem only.
And that doesn't cover the 80%* of questions we used to close with this close reason for actually being too broad.
How is the Fourier transform useful in signal processing?
is a single question, but we don't have a close reason for that anymore. It is parsecs to broad to be answered.
Can we fix this? It's a bug, since it effectively breaks the feedback loop between moderation and askers.
* like 82.34% of statistics, this number is made up
Also asking an equivalent question on EE.SE, since they are much bigger and might have a different view on this.
