Just defining the criteria for this list flummoxed us. Fantasy baseball? Too frivolous. A cocktail database? Not Chicago-specific. Svengoolie’s blog? Uh, no. We settled on listing those essentially local sites we thought would be most useful or interesting to people who live right here. (And we left off the most obvious, such as ChicagoTribune.com and SunTimes.com.) Of course, there’s no way we could ever have checked out everything. What’d we miss? Tell us in the comments below.
