I'm not sure that this actually qualifies as an ad hominem attack. In cases such as this, a lack of experience and expertise is a serious concern. True, there may well be outliers who, with little to no previous experience in a field, are able to master and advance it - but they are outliers. As to specific comparison with Santoshi and Bitcoin, it doesn't stand, due to the relatively poor history and documentation for LogDog and the relatively greater history and documentation for Bitcoin: There is the 2008 research paper that built upon well-known and well-examined previous work on electronic cash, anonymous payments, etc., etc., and there is the subsequent open source client. No one ever said "trust us, this is cool". Instead, they wrote detailed papers and code and released those to the world - and we made up our own minds. LogDog is, by comparison, sui generis, a thing of itself, that has sprung into being with neither preamble nor publicized foundations. URB may be the outlier. Or not. Given the lack of documentation, the lack of openness, and the apparent lack of expertise, we are but wise to raise the questions. So far, URB seems responsive and engaged, and not particulary evasive. Those are good things for that particular hominid.
