Right, so this Wednesday you can catch them all again for your next witchdoctor piece. Beware though, it's "Wednesday" relative to GMT time, not your own timezone, so be sure to look up GMT time before you go off and hunt jadinkos.
A lot of those older posts though have textual bugs, iirc, from the forum changeover. I know the posters can manually fix them, but a lot of them remain unfixed last I checked.
The thing is I honestly can think of very little that's both already in the game AND not used by a sizeable portion of the p2p population. I do get the point being made though, and I'll agree its a good one.
