I'll admit I don't read most of the posts that I upvote, I mostly support the people I appreciate having on the platform and who I believe help others stay positive on Steem.
I do upvote a lot of comments though on popular posts as well as on my/our own.

Proving my point, not really adding content discovery value
That's could be half true.
I do consciously curate comments based on the order I want them to appear. I.e trying to put the best arguments, most fruitful contributions to the discussion or simply the most interesting questions, to the top. So there I do add content discovery value.
As for posts, I simply don't view voting as participating in content discovery anymore. That because I know my vote means nothing in terms of getting things more seen (a problem Steem has had for as long as I've been here is that you either manage to push something to the top 3 posts on Trending, or your vote has 0 impact in terms of visibility). So this part would not change based on the number of votes I were to throw each day.
Edit: Oh, and I certainly read enough long-form news articles related to politics, economics, innovation, space and science etc elsewhere on the web that I would have been happy to read and properly curate on Steem.
