[Question] How should altruistic blogs be different?

I’m trying to get better at blogging—I’d like my writing to be useful to people, and I want to get better at making it more useful and reaching more people for whom it would be useful.

There’s a ton of advice out there, but much of is aimed at people doing this at least partly for profit who want to sell ads /​ product referrals /​ subscriptions.

What should a blog do differently if it’s just aiming to be useful? Some ideas:

  • organize content so it’s easier to find things by topic, not just newness

  • be more willing to not have snappy answers, to acknowledge stuff like “I might be wrong here” or “I’m not sure what the right approach is”

  • send full posts and not just teasers out by email. I still haven’t found a service that makes it easy to do this!

Do you have favorite examples of blogs or posts that do well at this?
