Although YouTube style microchunking appears to be at the bottom of the video foodchain in this matrix, that reflects the commercial video production background of the eyetag authors, and the true position of video microchunking really depends on the format/purpose of the video/conent (like these statistics videos for example).
Nevertheless, eyetag points to the increasing tendency of top-tier video providers to offer their content as microchunked webclips (e.g. BBC on YouTube).
Thanks to Andrew for the lead.
Meanwhile, the torrent (geddit?) of online video sites continues, with Chime.TV the latest wannabe which merges some of the features of Joost (but without the legal network content from Viacom, CBS, etc) with the channel-creation features of Splashcast. Like Scintilla which I wrote about yesterday, Chime.TV is another web 2.0 site that's late to the party. With no killer features, why go to the effort of switching to a me-too (unless I'm missing something here)?
