Aside from the Dis and their related channels, I’m subscribed to the following:

This Orlando life – Usually 30-40 minutes and details weekly adventures in and around the parks
Adam Hattan – Very similar to this Orlando Life
DSNY Newscast – usually 4-7 minutes of breaking news and rumors
Mickey Views – Similar to DSNY newscast but generally more in depth discussion as well as listener questions. Usually 30-40 minutes
DFBGuide – Disney food blog. Fun 7-10 minute videos about restaurant reviews and general food related stuff
The WDW Couple – a wide variety ranging from park videos to restaurant reviews. Usually 8-15 minutes.
