It's a tactic carried over from Josh's Bullshido days.
Now isn't that amazing.
Know who else was deeply entrenched in rec.martial-arts and bullshido back in the day? Oliver "usagi" Richman.
Usagi, Luke, and Inaba should start an exchange together.
Or a wallet.
Or wait, wait, I got it: a forex site. Based on "open source" code.
The more you know:
If you take the first 2 characters from "Inaba", characters 2+3 from "Usagi", and characters 3+4 from Luke, it almost spells "insane".
So, no, you shouldn't have them do things together. It would be almost insane.
