I think a video addendum would be welcomed if you don't feel too relunctant about it.

Maybe Penguin could plaster the embedded videos next to the tuts, once TWHL4 is out.
Ever since VHLT, a lot of them are outdated/incomplete. Take the detail textures guide for example; many mappers/modders think you can only use a grey palette detail tex, thanks to the ones coming with stock HL/CS 1.6.
Edit: Also not much love for SDK tuts around here lately, not that there wouldn't be enough of them floating 'round the web, still... A ton cs:go "tricks" i only see used in top notch maps.
