I think you're right about being in the minority. I don't think Facebook would need to exist if people didn't bother sharing parts of your life. It doesn't have to be self indulgent or self congratulatory at all. I rarely get that give from any of the people I have on my list. I like those people and want to know what they are up to.
Do you at least comment on the articles you reshare? I have a friend who posts articles often but doesn't fill in the part that would make it interesting to me- I want them to say, "wow! Check out this cool articles on sea otters! I had no idea they could do that" or just whatever motivation you had for taking the time to post the article. People are interested in *you*. That's why they are friends with you. Odds are thru could find articles on their own, it's hearing your perspective that makes FB at all interesting.
