Revision of January 2012 
I've just conducted a major revision of this article. Besides completely rewriting the lede, I've noticed a number of issues with the article, and I explain the rationale behind my editing choices with regard to those issues below:
 "Tendency", in the first line of the article, had a "clarification needed" tag. I was at first unsure how to "clarify" a word that seemed pretty clear to me. Nonetheless, recognising that those not well-versed in left-wing political terminology would have difficulty understanding what it meant in that context, I've linked it to School of thought as the closest alternative. If anyone can think of a better way to clarify its meaning, please do;
 This article used a mixture of Commonwealth and North American spelling. It has no clear national ties to any English-speaking country. As such, based on the Wikipedia Manual of Style's guidelines, I've standardised to Commonwealth spelling as that was both the predominant, and (as a search through the article's edit history will reveal) the first spelling variation to be used;
 There was a large amount of unencyclopedic language and (very) mild POV pushing. I've brought much of this article back in line with NPOV to the best of my abilities;
 I've italicised all references to the "Platform", as it is the short-hand of a book title. Additionally, it needs to be pointed out that "platformism" ought to be written with a lower-case P; similar to "anarchism" and "communism"; and
 Finally, I've removed all redlinks; as they make the article look unprofessional.
I hope everyone is okay with all of this. — '''''' Talk/Stalk
