Schneier is basically blogspam. Quotes entirely from another article, follows up with "I don't know what this means???" Why do people keep reading him?

Because not only is he a world renowned expert in his field he is also able to break things down for the common audience.

Here you are, reading HackerNews. Schneier is basically a good CryptoNews aggregation site.

He's a content curator for a particular category of content. Would you prefer to follow all of the relevant sources and sift through the cruft yourself?

But people should be submitting the original source, not Schneier's link, unless he adds something useful.

I can agree with that, however his interest in an issue is a primary indicator of its importance for me.

Reading a couple dozen different sources and summarizing anything interesting in them is useful.
