Taking your question at face value, I would much prefer information be "pulled" rather than "pushed". In other words, I don't want to be informed - I want to search when I decide to search, get reviews when I decide to get reviews, etc. I don't want someone else deciding how my attention is diverted or what they would recommend for me. A notable exception is that I am happy to take unsolicited recommendations from friends and family, but that's because there is a critical distinction: they want to inform me of something for me, rather than for the product manufacturers.
