It's important to bear in mind that it's really easy to find somebody
who claims to dislike just about anything, even if 99.9% of people love it. Some people will complain just to get in the paper or on TV. It's also really easy to find people who will casually oppose a development they have no real interest in, or don't stand to gain from, regardless of the development's merits.
The other perspective we tend not to see is that of the new residents. A growing neighbourhood is by definition more popular. For the one guy griping in the Herald there are hundreds of people who must not mind the "fishbowl", because they chose to move into those condos. None of those people were represented in the article.
Obviously there are people who have an unfounded negative attitude toward development, but they are the 5% or the 25% (who have the 1% or the 5% stake in a new development), even though they might send in 95% of the angry letters.
