Clippy, I must admit, I do think the probability of you existing is quite low -- about 0.5%. If you exist, then I certainly apologize for signaling your low status; as AdeleneDawner says, I am only speaking about you this way because I assume that you are a fictional character. If I believed you were most likely real, then I would respect you as an intellectual peer -- you seem to be roughly of the same order of magnitude of intelligence and respectfulness as the other participants here, and so I would treat you as a citizen of Less Wrong on that basis.
One way that you could effectively increase my probability estimate that you are real is to link to some purchase orders or contracts for paper clips or paper-clip-production-facilities. You can feel free to redact your personal information, if you wish. The point is that I expect Clippy-like beings who have existed for at least a Solar year to spend some significant fraction of their resources on paper-clip production, and I would expect anyone as intelligent as you to have substantial resources. So, I expect that if you are real, you will have invested in some paper-clips or paper-clip-production by now. Since humans are unlikely to invest significant resources in paper-clip-production, even for the sake of an elaborate fictional construct, your publication of paper-clip receipts would constitute evidence that you are real.
As high as 0.5%? As far as I can tell, Clippy has the ability to understand English, or at least to simulate understanding extremely well.
It seems extremely unlikely that the first natural language computer program would be a paperclip maximizer.
Some research says that lurkers make up over 90% of online groups. I suspect that Less Wrong has an even higher percentage of lurkers than other online communities.
