Podcasting, timeshifting, the iPod experience

This panel at Gnomedex spent some time talking about podcasting. At one point the question of bandwidth came up. Someone mentioned user experience problems for people with 14.4k modems. There's an important point here, something that no one on the panel brought up, and something that a lot of people---smart people---seem to miss about podcasting. Wait...wait...okay, I'm happy now. Scott Johnson did. Thank you Scott!!!

Here's what Scott said: podcasting is built on RSS enclosures. RSS enclosures are built on the idea of timeshifting. A well-designed news aggregator, if it runs every hour, won't immediately download an enclosure the first time it sees it in a feed. A well-designed news aggregator will wait until the middle of the night or some other time when the machine isn't in use. Alternatively, the aggregator will be scheduled to only run at off hours. The point isn't for the user to sit staring at it like a pot of water working its way up to a boil. Just the opposite. Connection speed can still be an issue, but it only becomes an issue when the product of file size times connection speed is greater than the length of time available.
