From Ross Rader's Random Bytes blog, here is an interesting way to make a major splash on a weblog by adding voice to it.  Ross was excited about this new functionality from Audioblog.com (he actually tried giving a demo during his talk about blogs at VON Canada last week, but the computer system was not equipped with multimedia). He signed up for the account ($5/month) and showed it around at his workplace as well, where his boss (Elliot Noss) also testdrove the system: 

I copied the above from his site, since I was curious to see how it worked, and now, I am pretty impressed with the quality (I wonder if they are using some sort of wideband CODEC like G.722, since the voice quality is pretty good).
