Should I use YouTube ?? Got any YT Guru's out there??

I'm thinking about buying a webcam today (my old one went to shit)... and Circuit City is up to 40% off now...

Should I start doing (article marketing), but with YouTube??
I mean, like make an informational video on a certain product or site, and have it link to a landing page at the end of the video??

How much traffic can you get out of youtube?? I've never tried it...

you will be able to generate a lot of traffic, if you can get the video on the first page. and if the products that you choose are the hottest products in the market.

yeah...
a lot of traffic??

is it all in the keywords that you use??
