I'm definitely a tobacco guy, and for me that means that's what I've spent the most time thinking about, reading about, learning about, spending $$ on since I started smoking a pipe. My guess would be a solid 80/20 split. Consequently, I don't really know all that much about the artisan pipe world, who the best makers are, the up and comers, etc. (beyond a relatively superficial knowledge).
This is starting to change a little bit, but only because I've largely met my cellar goals, and therefore my pipe smoking budget is less strictly devoted to tobacco acquisition. For example, I'm spending a bit more time perusing Al Pascia than I do on tobaccoreviews.
