Yahoo's lifecasting service has "launched" — if you can call it that. As we reported, Yahoo Live allows users to stream live video for users to watch, similar to the services of startups Ustream.tv and Justin.tv. This marks the first time that a major company has gotten into the lifecasting space. At launch, the featured user was "JT the Bigga Figga," but sadly, Yahoo seems to be running out of server capacity and is streaming only intermittently. Yahoo's Bradley Horowitz announced in his Twitter feed that "live.yahoo.com is, well, live... Help us crush it with load." I guess he wasn't kidding. If it decides to work, watch Splunk the Pony streaming live, after the jump. It's by far the most interesting lifecast I've ever seen.
