I have a tangential comment that doesn't really fit into either subthread,
There actually is a meta-comment thread going right now that is discussing the issue of professor friendliness. This would have fit great there!
I think you made a bit of a jump there from my statement that I like to know my professors as people, to some sort of assumption that this includes taking their advice in all things, and being part of an "inner circle". In fact, my OP primarily talks about how professors behave in class towards all their students. (with the exception of the mention a group dinner, but that was not the norm). Mainly if I am asking a professor for advice it would be for resources/books for a project. I don't know how you get from that to:
these kinds of contacts in your life can be dangerous,
I didn't say that you committed any mistakes of the sort I was describing. I merely pointed out that this is a common failure mode for those who establish some sort of relationship with higher-status people that goes beyond purely formal professional interaction, but falls short of achieving real insider/intimate status. I used the second-person pronoun only in the generic sense, as a less awkward replacement for third-person sentences using "one."
I also didn't say that this needs to involve any special status relative to the rest of the class. ...
One of the things I loved about studying liberal arts is that you actually got to know your professors. They would discuss their personal experiences in a topic ("Here's what I did during the feminist movement.."), you might get slide shows from their vacation in the country of study, or even invited to their house for a group dinner.
Going into engineering was rather jarring for me in that regard. The vast majority of professors would come to class, lecture on the topic, and that would be it. They might share what their specific field of study was, but they rarely shared any personal details. It actually made it harder for me to learn, because it was like "Who is this person who is talking to me?"
(I think a large part of this for me personally was because I am motivated by a desire to please, and so if I liked my professors, then I wouldn't want to inconvenience them by handing things in late, or bore them by giving them another sub-par paper to read. But that's another discussion...)
I've noticed that Less Wrong is similar in some ways. We may know about each other's views on particular topics, and general fields of study, but we know very little about each other as people, unless a personal topic happens to be related to a particular rationalist study. Even the intro thread set up here focuses mainly on non-personal information.
For example, a Generic Intro post right now would be something like: "I'm X years old. From place Y. The fields I study/want to study are Z. Here's what college/HS was/is like for me. I have akrasia." Pretty boring, right? INSTEAD, the things I would be interested in knowing about my fellow LWers include: "On my time off I enjoy underwater basketweaving and climbing Mt Kilamanjaro. I have 6 young daughters and a dog named Grrr. I love pesto. etc"
From a rational perspective, an argument could be made that it's easier to have constructive arguments that remain civil when you humanize the people you are speaking with.
I was wondering how other LWers feel on the subject. Do you like that our discussions are un-hampered by personal data? Do you like the idea of providing personal intros? Do you not want to provide personalish information for safety reasons, or because you don't think it's anyone business?
If you think you might need help writing a personal intro, I wrote [a general guide](http://lesswrong.com/lw/8nq/more_personal_introductions/5d4e) on the topic in the comments below.
Note: I predict there will be two types of response to this post. People discussing how they feel about this (Meta-Comments), and people giving personal introductions (Intros). To make navigating the responses easier, I am trying an experiment where I set up a meta-comment thread and a personal introduction thread.
PLEASE PLACE COMMENTS ABOUT THIS IDEA IN META-COMMENT THREAD, AND COMMENTS INTRODUCING YOURSELF IN INTRO THREAD.
Edited to make it more clear to focus on personality, hobbies, likes/dislikes, and NOT on what you study, or school.
