I'll counter. Don't tell my why you recommend it; tell me briefly what it's about instead and I'll decide for myself whether or not I want to read it.
I like to have moments to myself without feeling like I am being sold something. I feel like I am constantly being sold things on the internet; let me do the discovery myself. Let me decide for myself whether or not it is interesting to me.
If someone says why they really like a book, you can just... skip that part. If you post a list of titles with zero context, the only people you're helping are those who just want a list of titles, which is almost certainly the minority.
