I actually like the slightly slower, curated speed of 10-15 posts a day, spaced out a bit, instead of a constant churn of thousands of things. Although, with HN you can get an algorithmic approximation of that via HN Daily. The main thing that's still missing is the "why you should care" blurb that's Slashdot's signature: not just a link, but a link with something about why it's being linked in the first place. I find titles to be a bit too cryptic for my tastes, and the use of only titles tends to promote linkbait titles.
