The second one. I'm manually creating the blog, and manually editing the first post to add the youtube video in. I'd like to aggregate the first post from each blog on the front page.
It would also be fine if I have to tag them and pull them using sitewide tags, but it would have to work with the code in the aggregator theme that grabs the "preview" image from youtube. (So you know what I'm talking about, here's the code that is put within the loop)
<?php $vids = get_post_meta($post->ID, 'vids', true); ?>
<a href="<?php the_permalink() ?>" title="<?php the_title(); ?>"><img src="http://img.youtube.com/vi/<?php echo($vids) ?>/2.jpg" alt="<?php the_title(); ?>" width="130px" height="97px" /></a>
The theme requires a custom field called "vids" with the value being the youtube ID of the video, which allows it to grab the thumbnail from youtube.
Thanks,
Andrew
