Even though the site has recently been mentioned in a wonderful book, and the "About" page laments a similar site stopping their interviews, I'm putting the site on hiatus for a while. I'm finding it hard to find the time to send out queries for interviews, and then to follow up on getting the answers back. If I can find the time in the future, I'll start up the interviews again.
I still have a few interviews out in the wild, and if they do get returned, I will add them to the site right away. I just won't be reaching out for new interviewees anytime soon.
In the meantime, if you're looking for something similar, I have a few recommendations. First, Teoh Yi Chie of Parka Blogs has been doing interviews with artists about their tools. You can find his interviews here: http://www.parkablogs.com/tags/art-tools-and-gears.
Second, Dan Berry has been conducting some wonderful interviews with artists on his podcast, called Make it Then Tell Everybody. It isn't strictly about tools, but he often asks the artists about theirs. In the archives, there are several interviews with artists that have also appeared here on this site.
