[meta] Does Twitter really feed our "intellectual curiosity"?

I feel bad for posting a meta discussion, but I count 11 Twitter headlines in the top 150 headlines on News.YC right now (12 counting this one, unfortunately).

Does Twitter really represent ~7% of the interesting topics that can be discussed on this board?

"The focus of Hacker News is going to be anything that good hackers would find interesting. That includes a lot more than hacking and startups. If you had to reduce it to a sentence, the answer might be: anything that gratifies one's intellectual curiosity." (http://ycombinator.com/hackernews.html)

If I'm the only one who feels this way, I apologize for posting something that doesn't add any value, but at least I'll know.
