Since it seems likely that we'll have a set of pictures of just walking along, I thought this was a good time to interject this. I've seen some references to this thread and so on being a religion, and I suspect there's a bit of a tongue in cheek nature to it. Although there is certainly some semblance of ritual and references to heresy and Randall as god, I don't think, for most of us, that we actually see him as god, except in the sense that he is certainly a god over the Cuegan-verse.
If you do really revere him in that way, or see this as a religion, I apologize if anything I say offends. My goal is not to offend, but rather to comment on what I DO think has been built here. An earlier poster made a comment about "community" and certainly a community has grown up around the Time comic. This isn't the first community spawned by xkcd (see geohashing for another example.) More than any other examples, though, this community has built something around Time, and what it has built, imo, is CULTURE. We have a set of unique traditions pertaining to both the every day and the unusual. We have language, our own unique ways of communicating. We have our own cultural referents, leading to humor and serious discussions which are obscure to those who don't understand our culture. We have a set of behavioral standards and cultural norms which all are expected to abide by. The lack of flame wars is a good indicator of the strength of some of the cultural taboos. We have special events around which are built a set of traditions and rituals. Like most cultures, members of the community can embrace the culture to a greater or lesser extent, depending on their own desires for such things.
What is also fascinating to me, is that like most cultures, the cultural aspects evolve over time. But, in this case, two things are unique. One is the rate at which changes occur. Two, is the ability to trace and understand the origins of traditions, and to follow how language, tradition and ritual change over time. It isn't possible to trace exactly how the tradition of shaking hands started, but if you want to know how popes got started, or where the word "molpy" originated, or trace how Blitzer behavior has changed over time, you can do all of these things.
This last paragraph is more purely speculative than the rest of this post, but I suspect that many of the members of this community, at least those who spend a lot of time here, participating in all aspects of the culture, might not have strong cultural roots outside of here. This is based partly on the types of person I suspect are attracted to xkcd, and partly on what drives someone to spend significant amounts of time here. Again, I mean no offense, nor do I mean to over-generalize. Instead, the point I am trying to get around to, is that one of the more beautiful aspects of XKCD and this comic in particular, to me, is that it HAS (whether Randall explicitly intended this or not) created both a community and a culture, that provides a place for people to belong, to enjoy and to PARTICIPATE in the evolution of the culture. Of course, you can also just participate only in the more "puzzle" type aspects of Time, if you want to just come on to participate in language deciphering, or whatever, and don't really need to dip into the culture that's been created. One of the cool things about this thread, is that it's completely acceptable to participate in that way too. For those who participate in everything on here, I hope you appreciate and value the cultural experience this provides. I personally enjoy working out stuff about the comic more than anything else, but find it fascinating, and very cool, the way a culture has grown around this.
