I've yet to see any proof that Tez actually took it. Most of the supporters seem to be bandwagoning, save a few who actually know what they're talking about.
So I'm with Tez on this, although I would like to see the little chink skinned and turned into a rug.
My word:
I saw Tez using this for his DM, I was there over an hour, then, he changed to trench digging about 10 minutes before cucu came to check it out.
My proof:
Over 20,000 bricks with Tez's BL_ID on them.
