The person who sent me the request for research findings has further specified what he wants to know. Saddened that all respondent to date have either shown off their "cleverness" or asked for further specification. Not one even tried to answer the question. Concomittantly, I am reading _I'm Feeling Lucky_ by Douglas Edwards: an insider's ethnography of the early Google days. A repeated thought is that the developers kept moving forward with partial procedures. PS: Anyone else old enuf to have the phrase "Douglas Edwards and the News" resonate?

It would be nice to remove people who contacted ego both ways...there must be a way to do this without making the questions unduly cumbersome... A repeated panel of course could help to clarify issues of causality, since presumably both mood and the number of recent contacts vary over time... Experience sampling as developed by the Chicago psychologist Csikszentmihalyi might specify the matter in terms of contacts within the last hour or two and its impact on current affect. It would be nice to know if somehow has already some this or something like this.
