<p><em>askubuntu</em> is based on <a href="http://stackexchange.com/">Stack Exchange</a>, a free closed source platform available only as a hosted solution, i.e. no in-house use (see <a href="http://meta.stackexchange.com/questions/15753/stack-exchange-for-in-house-use">here</a>).</p>

<p>So, the answer is no, you cannot use it for your personal website.</p>
