Great Witch House connected Tumblr here, all remixs and layered videos and stuff (has a real life picture of Balam Acab, its like when Kiss took of the face paint and you could see who they were ..I imagine so anyway.) http://bonejam.tumblr.com/
Serotonin Sounds has a great interview with one of my favourite musical artists at the moment, †‡†, who talks about the whole Witch House scene, how Pictureplane invented the name, the other artists he likes etc. http://serotoninsounds.blogspot.com/2010/06/interview.html
The Flickr account of Alison Scarpulla has some awesome photos that rock a whole Witch House in the day/chillwave at night feel! http://www.flickr.com/photos/aliscarpulla/
Finally if you're a fan of Witch House and modern industrial sounds too then check out the Darkwave Tumblr.
