Was just reading Heliocentric's Journal on The Slashdot Blackout of 2004. The history is mentioned there. The orignal dates in 2002 were April 21-27, to be Sunday through Saturday. Heliocentric wants to change that to this month. I disagree on two points.
One, the idea of a Slashdot Bloackout is interesting. However, if people call it for specific reasons, it begins to be silly. The reasons themselves stir people to do it, yet it is actually done for two main reasons. One, to show people a stance, which is noticed by admins with the lost load, and the people with the lost comments, and two, to mess with the moderation system, which is decided based upon the heavy usage. Should the "heavy" users be perturbed and decide to participate in the blackout, the "moderate" users become the extremists, and that jiggles the system.
Therefore, calling it for a reason is something i object to. People should advocate the reasons to get people perturbed, but ultimately the reason it is done is because people are perturbed, regardless of the actual reason. As such, changing the date would seem incongruous with its goal.
Two, changing the date based on who calls it would seemingly not be effective. Should a blackout actually work, others would want to call it on their dates, and unless people follow a specific leader, the blackouts wouldn't be at the same time, and it would not be effecticve. Thus the contradiction. If it is not effective, it is all on the same date. If it is effective, people will have it on different dates. Considering this problem, changing the date would be a "Bad Thing". Let's leave it where it is, at April 21-27, whatever days of the week they fall upon in any given year.
