This of course depends on whether they time enough, of course - but my firstvote would be if Toby would occasionally write a brief outline on how certain individual visuals work/are implemented. Like, How Does FunnelWeb Work? or How Do Stickmen Dance?

Another one would be John G. on the Equaliser. Mike on how builds are done. Rob on how to be PHB at empeg/Rio. Hugo on anything (We Are Not Worthy). Roger on various aspects of Emplode, about the single most useful bit of software for the player (and other products).

Roger has a ton of cool stuff at his homepage... Lots of it technical software dev stuff..
