Seeing as we already have multiple “convention” related posts (See: Writing conventions) in the Wiki category, I think this would be a good time to mention that the Wiki format allows editing existing contributions.
As someone that worked for big companies that utilized Confluence, the one thing we do not want is to fracture content in ways that cater to:
- Risk of repetition that leads to persistent stale content.
- Risk of convoluting information.
- Risk of convoluting the process of contributing.
- Treating the Wiki section as a disjoint messaging forum.
A Navigation index is alright, but search engine indexing could still prioritize topics themselves, and then we enter into the realm of, “This is outdated, let me make a new updated version”, or “This is not quite what I was after, let me make another topic about this” without a search. Also, the Navigation index needs to be updated for every contribution… and well… now we have another avenue of error.
TL;DR: Let the Wiki topics themselves act as the index, properly itemize content, and update the proper topics with the information. Let us keep the Wiki clean, concise, and easy to maintain.
