why should left joins be bad?

but here, it's suggest a inner join

PHP Code:

$projects = $DB_site->query(" 
        SELECT COUNT(*) AS votes, project_rate.projectid, 
            projects.text, projects.timestamp, user.username
        FROM project_rate
        INNER JOIN projects ON (project_rate.projectid = projects.projectid)
        INNER JOIN user ON (user.userid = projects.userid)
        $clause
        GROUP BY project_rate.projectid
        ORDER BY project_rate.projectid DESC 
        $limit 
"); 
while ($project_info = $DB_site->fetch_array($projects))
{
    $project_info['text'] = nl2br(stripslashes($project_info['text']));
    $project_info['num_rates'] = number_format($project_info['votes']);
    extract($project_info);
    $time_posted = vbdate('n-j-y, g:i:s a', $timestamp); 


that should work i think
