Do you review?

I think it's safe to say that we all rely pretty heavily on product reviews but do you review products? If so, how? Do you review everything you consume? Just things you like/dislike? Where do you post reviews to? Where you bought it or where you get the majority of your reviews?

Personally, I will review products with very few reviews or products that seem to be cult favorites but didn't work for me. I'll usually post them to Target/Ulta/Walgreens and maybe to the product's brand page if they made that big of an impression.
