Also I have to call you out on something, you do run a service that cuts out the need of a bitcoind at all. It is ironic you want more node participation when your whole business model is cutting that setup out.
That is not at all our business model. Strengthening the Bitcoin network in every way possible is in everyone's interest, including ours.
You do make it so people/companies don't have to run a full node, so you are contributing to this issue. The network needs companies like yours making it easy for some people, but I disagree companies like wordpress and reddit using your company those are two companies that could really strengthen the network by running a bitcoind as the backend.
I doubt Bitpay is preventing Wordpress from doing anything. Maybe they'd like to see a few bitcoins come in before they invest more.
Regardless, Wordpress acceptance of bitcoin dwarfs their potential contribution to network health.
