I find that I often join a forum, post a lot, and then once the game grows old on me, or the forum, then I move on.
I have found that most of the folks here, barring the people who complain incessantly about every jot and tittle in the game, are good folk who love a good game and want to gab on about it. I have joined in the last month or so and I hope I'm not considered one of the loud and annoying. I'm here to actually learn a thing or three from the experience of others who play this game, and also have fun just posting and having a good conversation.
I think age and posting does not have too much correlation. I think age and posting to particular forums may have, but that may well prove just as dubious. In a forum that is for a gaming community that is diverse, such should be reflected in the stats. From what I can tell, this holds true here. It is predominantly 20-24 year-olds--the majority of gamers. Folks in their thirties are old-school gamers, but probably hard-core nontheless (i am friends with one in particular). Older gamers are people who love a particular type of game usually...though there are many who just love games in general. I think the demographics on this poll reflect the demographics of game players in general, not just for CivIII (though that is mostly unqualified, i'm only musing here). As to age demographics and topic-related forums, I think you're going to see people of similar ages on different sorts of forums. My guess is that you'll see a wide variance in age in boards of general discussion, religion, and world events, but it narrows down as you get into narrower categories of interest. You're going to see a certain trend in a Britney Spears forum versus the trend you'd find in a forum for World War II discussions (though it would be most interesting to see what correllations would exist between two such vastly differing topics of interest).
I could go on speculating and musing as to all the social/psychological/intellectual ramifications that may be gleaned from further study of internet forum posting, but I am not an information science major. I am, however, a communication major, so the use of these forums does interest me, as a cultural phenomena and as modus operandii for many a computer-jockey. What sorts of relationships are built by these things, who uses them, what do people talk about (that's a limitless one, i think), what sort of interactions are typical, abnormal, etc., what sort of community does it create, how does it fit into the larger society, how does it impact personal views, psychological functions, etc., and what sort of inferences, conlcusions, and lessons can be drawn from such questions and engagements with the study of all such manner of communitas and diffend? On it goes...
Well...hmm, that was more than I wanted to say. At the very least it should give you something to think about and more to write about. Perhaps, if more discussion is catylized, this topic could be moved to the off-topic area, for further discussion of the ancilliary and peripheral aspects of the commicative-cultural interaction and social economy of internet message board/forum groups. Cheers!
