There've been so many articles lately on gentrification that it's been dizzying. Most have covered ground that people have written about for years, and repeat tired cliches on all sides of the issue. I confess to be tired of the old arguments, precisely because I think we're in a different era now with different concerns than 20 or 30 years ago. I even strongly dislike the term "gentrification" since it's a British term describing a particularly British phenomenon - then applied to American cities. Personally, I think Megan McArdle's recent writings have been the best - especially this, this and this. The last one is outstanding, and it's interesting of course that someone who's not a planner has a better grasp of this than many planners. At any rate, below is a tweetstorm from today regarding another aspect of the conversation.
