Are the Q&amp;A posted on Stack Exchange websites valuable consideration?
<p>In order to form a legally binding contract it is necessary that both parties provide valuable consideration.</p>

<p>Is the provision by a user on this (or other Stack Exchange sites) of a question, answer or comment "valuable consideration" sufficient to form a contract?</p>

<p>Yes. There's no requirement that the consideration be objectively valuable, as there's no real standard for value; as long as there is some consideration, it can be offered for a contract.</p>

<p>The <a href="https://en.wikipedia.org/wiki/Peppercorn_(legal)" rel="noreferrer">peppercorn rule</a> states that nominal consideration is sufficient to constitute consideration for the purposes of establishing a contract. Even if later, we decide that the comments or posts are no longer desired, it does not cease to be good consideration.</p>
