I was wondering about the specific mechanics of a Diablo 3 item, and decided to ask a question about it. When checking if the question had already been answered (SE search, Ask Question -> type in title and see suggestions, and lastly a google search), the google search led me to the answer in some Reddit discussion.
What should I do in this case? Should I post the question I originally had in mind along with the answer I found, to improve the "completeness" of Arqade?
Reading on this issue, I found that the consensus is that self-answering is encouraged, as it helps promote the site and presents the information to people in a nice easy-to-read manner. However, I feel like it borders on plagiarism, as the answer is relatively easy to find through Google.
The Reddit source can be found here, for the particular question I had in mind.
