This would be helpful to know what the odds of having something actually be done with our ideas. That way, if we know there is only a 0.07 percent chance our idea will be used, then maybe we don't bother posting it. It would save us time and allow us to focus on enjoying the site rather than trying to imagine it as we would like it to be.
Posting any ideas here shouldn't be distracting you from the enjoyment of a site as a whole - but if you feel like something can be improved, please do make a post, then carry on with your life.
Nearly everything does get read, and well supported ideas normally are acted upon if feasible.
Everything else is up for consideration. (Complexity/time requirement/risk to stability/value to other users)
