(And yes, I know LOL is an ancient BBS-era invention.)
And speaking of roof top parties, last night I attended one two blocks away. The host, a 40-ish friend of a friend, has been living in the same Williamsburg apartment for 20 years. She also used "retarded" to describe how no one can afford to live in Brooklyn anymore. I'm not sure that I would call living in Jersey City or Queens retarded, but I appreciated the sentiment.
