Professional physicists often jealously guard their good ideas, since they are afraid that competing researchers might steal them and publish first. As a junior scientist, I am sometimes appalled by what lengths some colleagues go to to avoid collaboration, which is why I'm such an ardent supporter of websites such as this one that promote open and unreserved discussion of ideas.
However, what should a hypothetical Physics user, who is also a researcher, do if a discussion on Physics leads to that spark of inspiration which ultimately results in a publication? Pride is easily wounded (especially other people's ;-) and we wouldn't want people withdrawing from discussions because they think their ideas are too good! Our hypothetical researcher would presumably like to give credit where credit is due.
Will we see a new wave of papers in Physical Review Letters that say in the Acknowledgements section at the end:
The authors thank the community of physics.stackexchange.com for fruitful discussions.
How would people like to go about this?
