Usagi Yojimbo is not particularly my cup of tea, but it *is* a cult classic comic, and definitely 'furry' in the old school sense, if not generated from within the fandom. Arguably, and as Pi demonstrates, it's more well-known *outside* furry than within. From Conway's perspective, this has three positives:
-Bolsters their GoH cred (check out panels with big-name guests, they'll often say 'I was unsure about coming here, then they had me talk to Stan Sakai...')
-Is grounded in the oldschool 'furry fan' ideal that Conway was a part of,
-The comic is intensely kid-friendly, thus letting Conway push that good old 'AC is squeaky clean' image.
In other words, promotion, promotion, promotion. At least it's not as creepy as bringing in the DeCarlos...
