The Wall Street Journal says: "No self-respecting industry these days is without a must-read blog. Although they vary wildly on fine points like accuracy, they are now so widely read that it's assumed anybody in the business is up to speed on the latest postings. For outsiders, they are also a window into the inner workings, preoccupations and gossip of fields ranging from real estate to mergers and acquisitions."
Then it gives a run-down of the must-read blogs from Curbed.com ("attempts to deflate real-estate hype") via adrants.com ("one of the best ways to keep up on Madison Avenue's ups and downs") to www.rgemonitor.com/blog/roubini ("tracks monetary issues, among others, through a macroeconomic lens").
Separately, WSJ columnist Walt Mossberg has written Mossberg's Favorite Tech Blogs.
