Alright, so it's easy to dismiss an article like this, but let me offer a defense to those who denigrate it.
First, political consciousness exists on a continuum. The thrust of this article seems to come from people who have developed an enthusiasm to make things better. That is a good thing, even if you don't think their consciousness is where it should be. One can argue the merit or lack of merit of the effectiveness of their action, but they did something and if it puts them into a mix with others so that consciousness can be raised to deeper levels, then it is a good thing. Activists arise out of ones initially being involved, so why act like the left does much too often and throw water on others rather then seeing the potential. It is easy to criticize and much more difficult to work to move something to the next level.
Second, I often wonder how many posters at these kind of sites are actually involved in progressive/radical politics other than typing on blogs. Those who wrote this article are people who organized something and did it, they got out from behind a computer and acted in a way that can be built upon. So calling them foolish is naively foolish in itself.
Third, these people are building solidarity among themselves, and what the whole movement for systemic change requires is broad solidarity. They are making connections, among people and about the system. True organizers would see people like these who took the time and effort to do something as potential allies, as those who can help in the struggle. They may not agree on many levels, but they would engage them with respect, something not often seen on anonymous blogging boards.
Last, it the article recognizes that one must take responsibility, one must act, one must do something, one must be an agent for change. That takes more than just owning a computer with internet. That responsibility takes time, money, effort, and is filled with frustration. In short, it takes commitment. If these people stay engaged, they will be forever changed, maybe even grow a deeper understanding (like I did many years ago) in terms of having a better politics.
Just saying. We need to self analyze and vet where we are coming from and what we want to accomplish and how to move our interactions to the next level.
