I've always heard people suggesting that one should disable Adblock on sites that you like to support them. But I'd think most people who can will still block ads (I do; they're distracting). Trying to support the site by disabling ads seems to just encourage the site to continue using what will eventually be an ineffective way of making money.
Couldn't you make the argument that by disabling ads you're "voting with your wallet" and forcing them to find a more sustainable source of income?
