We have review blogs on here. Those are posted on blogs, not talk pages.

Here's links to a few of them.

User blog:KidVegeta/KidVegeta's Reviews

User blog:TeamUnitedNerds/Reviews... as they rise, I fall

User blog:Destructivedisk/D-Disk Reviews

User blog:Supersaiyian11/Ss11 Reviews (for a laugh)

I've never heard of anyone posting reviews on talk pages, but posting the link is quite common.
