As an experienced guitarist, I have a very simple idea that I believe is worth pursuing - at least as an experiment. In case it is a successful idea, I don't want anyone (including myself) to be able to patent it. I'm retired and I'd rather simply share the idea openly.
For mainly traditional reasons, the strings of almost every type of guitar fan out towards the bridge. I suggest that precisely parallel strings would be an improvement for some styles. In the following question I published my idea.
... I am publishing this idea here. If I have invented the idea of a parallel-stringed guitar, I don't want anyone to patent it (including me). This will stop any particular manufacturer from benefitting over others. I do not want any financial remuneration for myself if this turns out to be a good idea. This would apply to classical, acoustic, and electric guitars.
Is the simple publishing of an idea online, sufficient to stop others patenting the idea?
