Saw four cool demos this afternoon related to consumer media distribution. The first, Magnify.net, empowers online publishers to integrate user-generated videos into their existing web offerings. [We’re talking especially about the little guys here, not the big players as Brightcove tends to focus on.] The whole idea is to create high-traffic niche vertical content sites that will attract advertisers looking to reach micro-target audiences.

Yodio has an end-to-end audio publishing system that it’s used to create an online destination community for creating and sharing audio casts. “The future of the podcast is still ahead of us,” said CEO Clay Loges. All you need is a cell phone, a camera, and Internet access. Post an audio cast, for example, about a vacation you recommend, and upload photos, too. Sharing is similar to Flickr.

Blerts, an offering from ThePort Network Inc., is riding the rapid growth of RSS consumption, which CEO Bob Cramer says now numbers more than 30 million people. “But, even for those who subscribe to 100 or more feeds, only 5-10 are really important,” he said. Sound familiar? Blerts is the first graphics based RSS alert utility that notifies users when their most important RSS feeds are updated. It’s pretty cool looking, and you can download it now.

The Splashcast media syndication platform is “the first one that’s easy enough for everyone,” said CEO Michael Berkley. Create and syndicate an online channel of mixed-media content — music, photos, video, text, RSS feeds. The key is that it’s a universal web-based media player — you don’t have to install a player for every video you put on your MySpace page, for example. In about 48 hours of having the site live, Splashcast users have already created more than 1000 channels.
