Recently, I turned to "the internet" looking to answer an Excel question.  Over the past year, I have found myself gravitating directly to SE/SO to answer many of my technical questions (much like I did with Google and Wikipedia when they were new). 

My basic question was "how could I find/replace/remove hidden characters from text pasted into Excel cells?"  I found the answer [here][1]. 

In this case, I had to dig around outside the SE/SO ecosystem to find the precise answer I needed.  Now, I want to "move" the information I found into SE.  I just ran across [this Q&A][2] and [this page][3] which seem to indicate that I could just ask and answer my own question.  But, I want some community feedback before doing so (it doesn't feel right). 

So, what is the etiquette for ensuring this information is available on SE?  Should I ask/answer my own question?  Should I ask the question and wait to see what other answers users come up with?  Should I ask SE users to provide answers that are better than those on the [page][1] I linked above?

Thanks!
