On Aug. 6, Linda writes: “I hate to be the sore loser – but I have to be honest – I am constantly waking up in the middle of the night from the noise – the bus, train and ambulance sirens are understandable since we live in a big city – but I find the noise from those ridiculous scooters/mopeds and the people fighting or doing whatever they are doing at 3am in front of my house to be terribly annoying.” She also mentions another urban peculiarity: “I have also read about other folks being attacked.”

As bodegas get replaced by big chains, residents are starting to grouse about the incoming inevitable: the coffee chain. Few things are as divisive as where you go to buy your cup of joe.

At least one poster asks whether Columbia Heights Coffee is a truly good-for-the-people operation, and another grouses about minority-owned franchises.
