Worm's point I believe is that the basis of this community (TLS) is to share wisdom, experiences and resources regarding all things law school. Everyone benefits from the collective contributions on this website. If you don't feel like contributing to the pool of data, but want to benefit from others' contributions, fine, but making an account to say "In!" is insignificant and self-serving.
Do you show up at parties and not bring anything? I mean, it is polite to bring stuff, but I guess you don't have to...it just makes you a douche to show up with nothing and eat all the food.
For me a lot of the "food" is being able to hear from and share with other people who are super neurotic about law school admissions. At this point, I have lost friends and quite possibly the love of some family members from talking WAY too much about my applications. Just hearing about others' experiences is part of the draw for me.
Value of this vs. the actual information probably varies by user though.
I'll stop here to keep form hijacking the thread entirely, but Domino is getting at more of what I was saying, and that is to say this isn't a market in which the goods come in the sole form of dates and numbers which must be exchanged in equal parts to keep one from being self serving. Many people, even those who aren't comfortable sharing/are unaware that this is protocol, benefit others through other avenues of sharing experiences/feelings/anxieties etc. The ways in which one contributes to any community, TLS included, are too far reaching to be simplified as Worm put it, which is if you share numbers you are of value and if if you do not you are a self serving asshole.
That being said, if you create an account solely to say "In" and contribute in no other way, you are likely wildly oblivious or self-serving to be sure.
In any case, all opinions respected, I digress. Back on topic.
That is all.
