I think that’s part of the reason for the new set. Cecil originally focused on more Chicago centric topics, and those topics are much less likely to be answered in other sources.
The addition of Straight Dope Chicago was partly to go back to the olden days when Cecil first began writing his column. It was also partly to try out the idea, to see whether local-topic columns and discussion forums will attract posters/readers… and advertisers.
I agree; I find the Chicago-only columns to be at least as interesting as the “main” column. I think at least part of that is because a good portion of the general knowledge-type questions answered in the main column seem like a fairly straightforward exercise in using Wikipedia and Google whereas the Chicago columns have involved digging through newspaper archives or editorializing or both.
I think it should be pointed out that Straight Dope Chicago has a much longer word limit than the Straight Dope. This week’s column, for example, has more than 2,100 words total, compared to 838 for the Straight Dope. Cecil has much more freedom to expand and expound in the Chicago column.
Actually it’s been my impression that Cecil has done a pretty good job of going beyond Wikipedia. One would almost think that he practices solid science journalism… but of course he just knows all this stuff.
Also, I think the freshness of the Chicago setting may have inspired a lot of terrific questions. Creative Loafing should coin another trademark and franchise it out to NYC, LA, SF and other metropolises worldwide.
Google text ads aside, internet advertising seems to be limited to Yobba berries and vendors of overpriced gold coins. TPM is attracting a few lobbyists now, but I’m somewhat surprised that there’s no analogue to those who purchase ads in Popular Science and the like.
