Barclays Center (and complaints about it) lead NY Mag's "Reasons to Love New York 2012"; Jay-Z gets cited for DeNiro diss, viral video
Note that the text under "Because We Can't Go Two Weeks Without Peeing All Around It" is rather misleading:
By October 16, a “quality-of-life committee” had to be convened to deal with, among other things, rampant urination. Barclays opened September 28.
Jay Z gets mentioned twice, first for getting Robert DeNiro peeved (because Jay didn't come through on a promise), then for his viral subway encounter with artist Ellen Grossman.
