<p>As another long time user, I perceived two main usability problems:</p>
<ul>
<li>There are tons of <strong>zombie questions</strong> floating around, for which none of us has the rank to vote to close them.</li>
<li>If <strong>new questions</strong> are answered, they often <strong>don't get accepted or rated</strong>, even if the creator of the question is happy with the given answer.</li>
</ul>
<p>If a transition to another service solves those problems, I would welcome it.
Although manually giving trusted users the right to close-vote and adding the accept-rate-functionality from other stackoverflow-sites present two simple solutions.</p>
<p>As Ron already mentioned, the main problem is the <strong>low activity on the site</strong>, though. There are hardly any new and interesting questions which would motivate people to participate in this project more often.</p>
<p><strong>Edit:</strong> To round some comments up:</p>
<ul>
<li>A transition to another service is a good idea, if it makes managing and cleaning of the site easier.</li>
<li>The main problem is low site activity, and thus independent of the service used. A discussion on how to create more activity, or even why activity has faded, could be useful.</li>
</ul>
