How does this work?

If I were to post an Idea here, how would I know if anyone responded other than going through the laborious process of checking every idea I may or may not post? Do you know if you post an idea how many people have checked it who may or may not responded. I am basically brand new to this site and really impressed with the depth of dialogue here and would like to know how to use it best? 

Any long-term users figured out any information that could help a newbie? Also, has there been any mistakes you've made that you would advise others to avoid? Thanks for your time.
