Shilliber is a subscription service that allows you to call a preset number, enter a code, and then leave up to a 15 second sound clip. That sound clip, called a shill, is housed on Shilliber's servers and is exposed to the Internet.

I signed up this evening--it was an easy process, but then wasn't clear on *how* one sets up the ability to leave a clip. Finally I noticed that there is a link called, "Create a Listing". This apparently sets up a "bucket" in which folks can leave clips. You can choose to leave a clip on someone else's listing and then, the clip will be part of that person's listing. So, you could set up a question on your blog and then ask for comments on the blog.
