A sign of a news related topic in this industry is when you find a thread on the topic at most of the forum. But one thing I have been noticing way too often in the past 6 months or so, is that people are posting the same post in multiple forums. The most recent example is the news on "Google founders to offload 14 million shares". Here are just some of the forums I found discussing the same thing, with the same thread title and member posting.
Just to name a few. :)
