Radio Vox Populi proves a pretty brilliant idea. The site scans blogs, then reads them aloud using some sort of text-to-speech app (JAWS?) in both male and female voices.
It tired it and it's pretty cool once you get used to the voices, but it does tend to cut off the entries midstream, which proves annoying when you're particularly interesting in one - must give each entry equal time, I think. A sound comes on like you're changing stations and then another entry is read aloud. So, works best for short entries, I guess.
