Into the Ether -- which is published on the right sidebar of this blog and syndicated on several other sites -- needs more writers and more activity. To learn more about it go here. Basically, you can write short posts about anything you want. The point is to build up an ongoing conversation, a sort of stream-of-consciousness mini-blog. This other page has details on how to syndicate Into the Ether so that it shows up on your blog. It's easy (and free, of course), and will give you another source of frequently-updated content.
You don't need to be a blogger to participate, you just need to email me at plasticATgmailDOTcom.
