Vidnik is a new Mac application that lets you quickly record video from your Mac's iSight camera and then upload it to YouTube. Simply run Vidnik, set your YouTube account username and password, record some video, crop it, add some tags and a description, choose the video category, and then click "Upload."

The movies you record are saved as .mov files in ~/Movies/Vidnik so that you can use them for other things as well. You can also drag other movies onto Vidnik for easy upload to YouTube.

Vidnik is a good tool for video bloggers (who want to use YouTube's bandwidth instead of their own), video responses to other YouTube videos, and solo musicians who want to be able to quickly upload performance video.
