I'm new here and even as an an Anarchist i dig libcom's effort to educate about different strains of thought. Council Communism, Situationist thought...In America many Anarchists are quite ahistorical in their approach..Crimethinc's bullshit declasse pose does nothing to help this. Tho I like their effort to speak plain about Situationist thought, they are very obfuscatory in every other realm.
A class based anlalysis is important- although my ideas about class are not as rigid as say a Marxists or trad anarcho-communist. In the U.S., rampant consumerism and credit card culture seem to blur lines,,,yuppies think that they are strapped, when what they are strapped to is their own slavery to status symbolism. In the end, the plain-words of the Wobbly preamble seem to cut thru most of the shit...the working class and the employing class have nothing in common. Yuppies are employing, 'coordinator' class (that's parecon) and they don't really produce let alone create anything...the maintain the Spectacle, they maintain...appearances...
I know people who 'identify' Marxists but are not authoritarian in their manner or in their theorizing, there are Marxists in the IWW. Althoug i do wonder if they have shrines to the Moor in thier rooms...But I try to engage them in dialogue and usually
find it satisfying. As fare as all those "little Maoist, Stalinist, Trotskyist, and Guevarist piles.." (Vaneigem) I could give a rat's ass...though i do believe there is a crypto Maoist strain infiltrating the Anarchist milieu, and front organizations for the RCP have a lot of control over the antiwar movement.Scary, in fact. They don't even have the stones to tell people who they are. Only a lunatic worker in the U.S. would find a home in the RCP...but somehow, they have resources. My guess is that they are massively infiltrated by the govt., "Militancy" is easier to replicate.
Anyhow what I guess I'm saying is that in Europe , maybe, there's a larger consciousness of radical politics, lines are more explicitly drawn, some Trot is fucking ridculous but in the US no-one knows what a Trot is.
Anarchists need to start taking real initiatives in the community...I believe this to be libcom's motive, don't know them, but it's a good guess... without cramming ideology down throats...Americans would be receptive to autonomous federations of directly-democratic assemblies...and some form of worker's councils, the trade unions are starting to get wise, some of them..a rose by any other name. Collective labor has to compete with capital on its own turf for the time being. But it often stagnates in isolation. 
sorry i'm babbling
Can comment on articles and discussions
I don't really think "libcom" is mentioned that much at all (meaning no offence). Certainly, where I am from, very few local anarchists, and "activists", make real use of it. To be honest, I can understand why, despite the fact we have a fairly large, and active, anarcho scene. I think the forcing away of anyone except strict leftist, community orientated, anarchists plays a large part of this. The site functioned much better as a general anti-authoritarian resource - sure, push the class war side of things if that's what floats your boat, but in a constructive manner. An anarchist resource should be about open dialogue between different tendencies within the anarcho movement, rather than distancing the various strands (you ain't gonna convince 'em towards class politics if you slag 'em off to their face continuously).
On a personal level, I find the news coverage is good, useful, and informative. The forums, and the intolerance of anything but "class" politics upon it, however, is quite another matter.
As for a political role, I'd prefer the site to move back to encompassing other strands of anarchist thought (even if the majority here just wanna sway them towards class stuff). Otherwise, I see it as becoming nothing more than a group of twenty or so regulars using the forums, and a slightly larger amount making use of the news coverage but bypassing the site as a whole, leaving the whole project with little real input or relevance to the uk anarchist scene/movement. Which would be sad, as a passing thought.
Anyway, waiting to be dismissed as a "cock".
