I'm writing an application, and I get help on Stack Overflow for many of my code primitives. Somewhere in my application I would like to acknowledge Stack Overflow's "help" in building the application, and more importantly, mention the names (or aliases) of the specific Stack Overflow users that helped me the most with solid detailed answers, including links to their Stack Overflow user page. I believe in crediting people and I believe this credit is justified.
However, I realized that by doing so I may be exposing myself to intellectual property ownership claims by those users I'm trying to credit ("he just admitted I participated in developing this app, but he didn't pay me any $$$, I can sue!"). It's not that I'm saying the users will take advantage of my acknowledgement, but rather that from a legal standpoint it looks fishy and may open a door for problems.
To clarify, I'm not bothered by using the content provided in Stack Overflow—I'm not copy-pasting anything, and even if I did, I understand very well that I can freely use the content. What bothers me is that by mentioning names I'm somehow exposing myself in a different way than using content.
Has anyone bumped into this or a similar problem? I would really like to credit Stack Overflow and individual users.
