I've noticed recently that the Articles page is no longer accessible via link from... anywhere, and it'd be a total shame for this considerable nugget of gold to be lost to the new tl.net generation.
http://www.teamliquid.net/forum/articles.php
Since this page was updated randomly and the selection process for being in this section seems rather arbitrary, the page provides a pretty good cross section of the evolving progaming scene and tl.net's evolution in general. Particularly interesting bits of history include Rekrul's Korea Progaming Story, the progaming incidents threads 1, 2, 3, 4, 5, and the LiquiScoop Archives.
Of course, there's much more to the articles page than only interesting history. The hall of fame section on the bottom is full of comedy gold and the extensive interview, OSL, and MSL sections provide endless reading pleasure. Did you know tl.net personally interviewed BoxeR? Well, now you do! Explore the entire page for yourself and remember that tl's venerable age is a good thing, because that means there's plenty of entertainment archived in the nooks and crannies of this site.
