The prime reason for me to drop Slashdot as a news source is because it is slow to post stories. The stories you see there are generally days old, or even re-posted older stories.

Also, usually their blurbs don't add much to the linked article.

I still sometimes read it, but much less as before. With HN articles are submitted and published on the site almost instantly, and users can determine whether it is interesting. This is great.

Another thing is that Slashdot tries to focus too much on mass "sensational" news, whereas HN has many stories about open source projects, hacking projects, obscure new programming languages/paradigms. Again, much more interesting.
