In case you missed the launch of this much hyped blog from the former Gawker editor. http://www.dealbreaker.com/ DealBreaker is an online business tabloid and Wall Street gossip blog. It seeks to cover the personalities and culture that shape the financial industry, offering original commentary, news and entertainment.
Don't know if it's been posted already: www.dealbreaker.com Background article in today's FT. Page 20 of the US edition.
Warning! Shameless whoring ahead: Yet another trading blog. But seriously, I'd appreciate your feedback and comments. Just be forewarned that I'm still getting the hang of the technical stuff involved.
The problem with blogs is that they are becoming so prevalent that you have to sift through 100's to find a good one. Unless they have been around 6 months or more, I am not going to fool with them. Many are "here today, gone tomorrow". Trader-X mentioned above is great, and has been around a few years. As has Trader Mike. You can go to Technocrati and search trading tags and other tags to find more blogs that fit a particular interest.
