Expensive real estate habits + time to throw out the treadmill

A daily tour around the web through the eyes of a NYC vertical dweller:

• Another relaunch!  New York Magazine covers the new UrbanDigs.com.  “At its relaunch, scheduled for this week, UrbanDigs.com will be devoted to data analysis, allowing users, for $20 per month, to track market shifts by neighborhood and price in real time, create trend charts, and chat about what they’re seeing.”  It looks like the monthly real estate habit is about to become a little bit more expensive.

• Is the recent Manhattan inventory drought getting some rain?  A quick search of StreetEasy last night revealed 574 new listings in the past seven days, a big improvement from the slow, sweaty days of July and August. (StreetEasy)
• What factors make a residential building more sociable?  According to one broker, children and dogs can play a big part.  But looking at the picture in this New York Times article, we think that having a large number of young and single residents might also contribute. (NY Times)
• Don’t have space for a treadmill in your midtown home?  No worries, soon you’ll be able to play tennis INSIDE Grand Central Terminal   (at a rather steep cost, however). And we thought the food market was an interesting use of space! (Crain's)
• An UrbanBaby poster asks the question:  How big is your apartment and how many children do you have? While one poster is fortunate enough to share a 3400 square foot townhouse with two children, others are getting by with much less space. (UrbanBaby)
