Ask HN: How to monetize content on your own blog?

I've got some very well clicked/read articles on my blog and I wonder if anybody has experience with monetizing content like that.

There are hard paywalls and alike, but I thought more about some "soft" way to do it. 10 years ago I would have thought about flattr, but maybe there's something like that around today?

Any ideas, recommendations and first-hand experience?
