Where's the bluetooth microphone? And an archive tool?

Why doesn't someone make a wireless bluetooth lavaliere microphone? It would be perfect for Skype calls, and also make it easy to give a speech. The bluetooth would magically hook up to your laptop, the laptop could jack out to the speakers. If it exists, I can't find it.

While we're at it, I really need a TypePad plug in that would highlight relevant archival posts automatically. If you look to the left, there, in little teeny tiny print you'll find all the archives for the last several years worth of posts on this blog. But most of you will never read any of them, even though a few are sort of good. One or two are even great posts. So, without completely interrupting the discussion with extraneous links, how do I point deep into the archives?
