Chris would find it confusing. Is it a blog? but it's more image heavy? is it like twitter but with without a character limit and a clumsy comment interface? is this that instagram thing cool kids like?
If he could overcome the confusion, he'd love tumblr. He could share his crappy artwork, banter about stupid lgbtbbq shit and search for cartoon porn all on the same platform.
But then he pretty much does all of that on facebook and twitter already. Chris is too autistic to understand he belongs on tumblr.
