Ideally, I would pay for most online content
My ideal for this is probably something like Blendle which combines subscription and micropayments, and actually seems to work. It's expanding to Germany, and I hope it comes to the UK in the near future.
Oh, and I block ads generally, because they're incredibly distracting when I'm trying to read something. If a site asks me to unblock (which some do) then I'll try turning off the adblocker to see what happens. 95% of the time what happens is a bunch of animations, at which point they get blocked again.
I pay for Ars Technica, because that gets me complete stories in RSS (rather than just the first paragraph), and I like their content. But I don't read enough of most sites to feel I'd be getting my money's worth for subscribing to them. And I read far too many sites to make that feasible. If I'm going to read three stories per month from two hundred sites then I need a payment model that works for that.
