I associate this sort of list more with haflchan. The counter opinions are, in sum, read what you like but try to challenge yourself now and then. I agree with this assessment.
The most valuable thread we have here is the "ITT the last book you read" one. I think this gives a good idea what people in our own subculture are in to.
Maybe we should do a top recommendations thread of what people liked best, not what they think someone else should be reading.
If I were to go for a list of this sort I'd lean to recommendations of what is considered classic and meets these criteria:
1. Exclude works commonly pushed in high school settings. Not that these works are bad, it's just that, being taught to a tedium, everybody hates them. No point in recommending what will be pushed down one's throat anyway.
2. Works that are no older than the twentieth century.
Students of literature properly laugh at these exclusions. I don't exactly use this as a guide to my own reading either. My thinking here is in asking what could more regular folks be tempted to try, and that would be culturally, or educationally beneficial while remaining engaging.
