You don't want this here.
Cryptography is such an awesome fit for a Stack Exchange site. You really don't want to reach for this low-hanging fruit because of something "user interface design" allows — apples-and-oranges. UX's opinion-discussions are held within the context of evaluating aesthetics. That's not in the same scope of your garden-variety "what books should I read" questions. And frankly… their "what do you think about…" discussions are the low-hanging fruit of their site; It's certainly nothing to aspire to or emulate.
I just closed this question, but closed is not deleted. Please continue this discussion. If the community truly feels this is a good fit for this site, posts can be reopened. But I hope the community sees otherwise, so please read on —
It's difficult to explain why, exactly, these "let's make a list" question lessens the value of a site until you've seen it over-and-over again on 57 sites. There's nothing inherently wrong with asking an "I'd like to hear what everyone thinks about…" question; It's just that we specifically forgo asking these types of questions because they're simply not good fit for this type of Q&A site.
Asking a good question is hard. Cryptography is hard. But that's what makes this site so special. With discipline, you can keep this site focused on those long-tailed question of specific expertise that a Cryptography community will find so intriguing… instead of launching this site to the same uninspired questions that have been asked 100 times before on every other site on that subject.
This Cryptography site is targeted at experts. When a top expert arrives on your site, you want them to see a list of questions that says "Wow! this the site for me!"
Big List™ questions, on the other hand, have little to do with expertise. Asking everyone to contribute to a large bucket of answers means that it stops being a question of specific expertise and becomes a "poll" of the community. It doesn't even matter what the answer are. Answers start piling on; a disproportionate amount of voting accumulates; There's not even an expectation that any one answer will be better than any other. People vote on what they recognize. That's where the so-called "expertise" breaks down.
People who visit this site will emulate what they see. You're home page is your design. Questions about your "favorite website" will inspire yet another "favorite book" and "favorite blog" post, followed quickly by "favorite podcast" then "must-have software", "best tool", "most egregious security laps", "funniest joke", "most annoying coworker" … on and on. It's best just to avoid this variety of question altogether.
Don't aspire to the same trash you see on every other phpBB forum on the Internet. Don't aspire to the low-hanging fruit. You don't need it.
