Most designers use this trick to have custom styling and avoid the annoying feedburner button.

Simply copy and paste this code anywhere you like most likely sidebar.php: 

[code lang=”php”]

$whaturl=”http://api.feedburner.com/awareness/1.0/GetFeedData?uri=your feedburner id”;
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $whaturl);
$data = curl_exec($ch);
curl_close($ch);
$xml = new SimpleXMLElement($data);
$fb = $xml->feed->entry[‘circulation’];
echo $fb;

[/code]
