I produced a custom publish type known as article. I'm able to create articles and things are working fine. However, I've questions about the feeds.

1) How do you begin to see the latest articles I produced inside a feed?

2) How do you see all of the blogs and articles all-in-one feed?

You can include this code for your functions.php file

function myfeed_request($qv) 
   if (isset($qv['feed']) && !isset($qv['post_type']))
     $qv['post_type'] = get_post_types($args = array(
                'public'   => true,
                '_builtin' => false
     return $qv;
add_filter('request', 'myfeed_request');
