Evolution of trust

(main point: "we have analyzed the evolution of the advogato community (the only one in which trust is explicitly represented!!!!) and trust decades over time (of course variance in trust increases)

Is this the case with every community in the world? What does this mean? Is it normal? Healthy? Does it happen also in real reality? (cite the influential book "bowling alone")

Possible titles:
 * Evolution of trust
 * Trusting Alone (pun on "bowling alone")
 * Bowling and trusting alone (pun on "bowling alone")
 * Bowling alone and trust decay in societies
 * Bowling alone and trust decay in communities
 * Bowling aloner as time passes by
 * Over time you bowling alone and aloner

Introduction
We explain what is trust, trust in society, ... si puo' copiare da vecchi paper.

What is advogato and similar communities and how trust is modeled (1 sentence).

What we have done? Analyzed trust statements evolution in time

Empirical analysis of trust in communities
and goal of trustlet in general

and of this paper in particular

Results
Main point: (global average) trust decreasing on a community as the community growsm, variance increases

At the beginning, the community is a small and tight set of people who know each other

(TODO MAYBE: check on essembly.com - many papers recently analyze it, check if the dataset is easily downloadable! essembly is a political site, there is a lot of "I don't agree with you" in it)

Conclusions
ex: CS, advo,

Idea:

is (global average) trust decreasing on a community as the community grows?

ex: CS, advo,

What about other measures? How the graph evolve over time? Powerlaw? Connected component? Reciprocity? ...

The importance of social trust has become widely accepted in the social sciences. A number of explanations have been put forward for the stark variation in social trust among countries. Among these, participation in voluntary associations received most attention. Yet, there is scant evidence that participation can lead to trust. In this paper, we shall examine a variable that has not gotten the attention we think it deserves in the discussion about the sources of generalized trust, namely equality. We conceptualize equality in two dimensions: One is economic equality and the other is equality of opportunity. The omission of both these dimensions of equality in the social capital literature is peculiar for several reasons. One is that it is obvious that the countries that score highest on social trust also rank highest on economic equality, namely the Nordic countries, the Netherlands, and Canada. Secondly, these are countries have put a lot of effort in creating equality of opportunity, not least in regard to their policies for public education, health care, labor market opportunities and (more recently) gender equality. The argument for increasing social trust by reducing inequality has largely been ignored in the policy debates about social trust. Social capital research has to a large extent been used by several governments and policy organizations to send a message to people that the bad things in their society is caused by too little volunteering. The policy implications that follows from our research is that the low levels of trust and social capital that plague many countries are caused by too little government action to reduce inequality. However, many countries with low levels of social trust and social capital may be stuck in what is known as a social trap. The logic of such a situation is the following. Social trust will not increase because massive social inequality prevails, but the public policies that could remedy this situation can not be established precisely because there is a genuine lack of trust. This lack of trust concerns both "other people" and the government institutions that are needed to implement universal policies.
