I am in the preliminary process of analyzing my reader survey of favorite sources on tech news. The good news for The Washington Post is that they are a favorite source of technology news, only CNET had an equal number of respondents. The bad news for the Washington Business Journal is that not a single respondent named them, even though it was a prompted response.
The Washington Business Journal concentrates too much on venture capital and merger and acquisition and too little on technology itself to attract readers. The subscription wall is also a huge barrier for a technology audience. With all of the IT trade press offering free access, it is a little difficult to persuade techies to pay for a subscription.
