Since the 800-pound gorilla in the online video world is YouTube, it makes sense that it dominates the news. To make them easier to digest, we’ve cut a number of YouTube news bits down to consumable size.

• YouTube has signed up Southwest Airlines as a partner for another user-generated ad campaign.
• A former MySpacer launches ChannelMe in the hopes of drawing creators away from YouTube by offering custom .tv domains.
• Matt Marshall at Venture Beat takes a long, hard look at the relationship between YouTube funders Seqouia Capital and Artis Capital, both of whom scored big in the Google sale.
• And if you were wondering, the videos featured on the YouTube homepage are not paid placements.
