Google Real-Time Twitter Search… Sort Of
I found a link to a MT-Hacks post [via Microplaza, which is another pending post] describing a greasemonkey script that brings real-time Twitter search directly into Google search results:

twitter search results on google - Google Search, originally uploaded by Stowe Boyd.
I installed the script, created by Mark Carey, and it seems to work, albeit somewhat slower than the native Google results do. Neato.
