My new web site SocialTrade just had a couple of nice new improvements I wanted to let you know about. First, on the home page, you can now add a comment for any particular item just by clicking on the comment button. You don't have to "drill down" to the item anymore.
Second – and I really want to encourage folks to use this one! – you can rate an item (anywhere from 1 star, worst, to 5 stars, best) directly from the home page. Just one click, and bang, your judgment is there for all the world to see!
