I just wrote a posting last Friday about Yahoo's video new offering that competes against YouTube and other similar video search sites that invite consumers to post and share videos.

Well, it did not take long for a response. YouTube has tweaked its site in response to Yahoo's move. YouTube members can now aggregate videos that they created or they can assemble a collection of video from other sources. The changes are a strategy to encourage communities around user-created and curated channels.

YouTube will also invite members to upload a video in response to another video on the channel where they find it. Additionally, the company is offering a tool that will enable users to more easily link videos inside blogs and measure the number of times the videos are linked or embedded on other pages.

YouTube now attracts about 50 million views and 50,000 video uploads each day.
