YouTuberzzz...

Both services are based on taxonomies for online videos, they are video sharing services. Beside being shared, the videos can be rated and watched without having an account but uploading would required an account in both cases and free of charge but some videos are for sale through Google Video Store. Both services provide the option of uploading videos on blogs and websites
One interesting thing about the videos, they are mainly made by amateur using mobile devices and in some instance the quality of the image pretty poor especially on Youtube. Embeding videos in Youtube is pretty straighforward and i played around with some of the options provided, managed to resize the video to make it fit in the right margin of the blog.
The ability of sharing videos, or getting Tv shows, movie clips, music videos, etc for free and easily downloadable are main factors that have made YouTube famous.

How to save a YouTube on a computer for offline use? I guess that wasn’t a great idea to give that insight, all along I’d thought YouTube clips couldn’t be saved but now… My hard drive is almost full with these clips I couldn’t get from limewire or other sites. Briefly I’m gonna share my discovery:
go to http://www.savetube.com/
download the following applications :
an FLV player
FLV to AVI or MPG converter
find the video to download and copy the URL from the address bar
go to SaveTube.com and past it into the Video to Save bar and click on “Go”
save the file with the flash video extension “.flv”
enjoy your video…

I checked some of the movie traillers on itunes, I ended up going to watch " I am Legend" by Will Smith, i was pretty impressed by the quality of both the image and sound in the preview at 1080p, i tried also 720p and 480p, as the number decreases, the quality is affected as well.
