I prefer the approach of being a tightwad and not paying. I doubt there’s anything that I wanted to read so badly that I would pay for it. At this time.
It’s hard to say where sites with a paper equivalent will eventually go.
There’s the argument that more people are choosing to get their stuff online, sounding the eventual deathknell of the print publication.
If that’s the case, journalists need to get paid somehow.
I’ve read about one scheme (no idea where) that suggests that people would pay tiny amounts for a single article.
There’s the thought of integrating, so if you have an online wallet, you would probably have access to everything. It’d be no more different than deciding whether you wanted to pay for coffee today, I suppose.
I think the more interesting thing to think about is that eventually, paper publications will die. We’ll all have the equivalents of electronic newspapers or something. And you’ll still have to pay somehow. If you don’t pay, you’ll pay through being subjected to advertising. When it comes to that, I’d rather pay.
But for now, embrace being a cheapskate. You have plenty of free options, even if they’re not the options you want.

I’m at least waiting to see if people don’t regularly reprint the editorials somewhere else. I will sorely miss reading Krugman and some of the others.
