The city is rallying in an effort to spread open/closed/cancelled/out/not out information about the city. Mainly on (so God Help us) TWITTER.
We’ve been updating regularly ourselves (follow us on http://twitter.com/brightestyoung) but here is a handy list of people to follow for constant updates:

• dcist_updates and welovedc have (predictably, and thankfully) taken on the practical approach: snow cleaning, roof problems, electrical outages, etc
• nycnell and byteatdrink has great updates on service industry specials, and openings and closings
• districtinsider has taken on the role of both snow trivia (ie how to make snow ice cream etc) and event updates
• capitolhilldc has great hill centric updates about both about restaurants and bars open (matchbox, tunnicliffs, art & soul…) and other public infor on the hill
• candrews of washingtonian (who has some great snow day specials scoop) is tweeting bloomingdale neighborhood updates
• dcra for always good basic info
• wcp for open/closed venue updates
• capitalweather for you know, weather updaes (which are not looking good right now)
• goingoutgurus for sledding advice
