(I know at least one of those was someone daring to ask if Google counted as a Guest when they're spidering the forums)
I don't know if it does or not...I know search engines used to have a footprint, but I'm guessing the forum code's been updated to ignore Google Itself.
Which just means there are more people viewing the forums (from school, on someone else's computer, etc) than are logging in to respond. In a sense that's a good thing - less password theft from "That wasn't me! My former friend across the street still had my password from when I used his computer back when we were still talking to each other!", but on the other hand a lot of conversations suffer from Lack Of Interest.

And some from being shoved into Future Improvements, because godforbid anything novel should be considered Of General Interest.
