Assuming I maintain or know a contrib module that solves a specific problem, which has not been expressed as a question on this site yet.
Is it acceptable to post a question + answer that expresses the use case and the solution, pointing to the module?
I imagine there is a fine line between information and spammy advertisement, even if this is for a free / OSS module.
Personally I'd say when doing this one should
- Only ask questions that could be genuinely asked by a real person, independent of the solution existing (see the comment by mponadio).
- Mention other solutions than just this one module, if they exist, and attempt give a fair overview and comparison.
- Mention that there might be a personal bias, e.g. if one is the maintainer of the module.
With these criteria being respected, where is the limit?
Can an otherwise valid question get a "bad smell" based on the author's motivation?
