For those of you who don't know what Shopcasting is (don't be shy, be proud of the fact that you have a life outside of the internet), I'll help you out.
NOTE: You are on an old site. Find this and all new posts here
Shopcasting is very similar to a blog, only in addition to describing or showing the item, there's a direct link to purchase that item.
I've listed some links on my sidebar where you can check them out.
If you're fortunate enough to find a site where the bloggers or participants have similar taste to your own, it can save you hours of websurfing, because they've done the work for you!
