I primarily read the HN RSS feed, and also try to look at every headline that comes across the feed to make sure I don't miss any godo stuff. I became curious about how much in the minority I am in doing this.
I used to have this OCDish behavior with HN & twitter, but then it took too much of my life.
Since I stopped both, I sleep more and consequently code better.
Some gems don't get upvoted, and that's ok; I'll discover it eventually somehow. In twitter's case, the signal to noise ratio just doesn't cut it for me at this moment.
I also follow the RSS feed headlines nearly realtime in Google Reader. I was surprised to see that Hacker News has four times the amount of submissions/day than other feeds I follow:
Surprised, because I have no problem keeping up with HN, while I often have to skip other feeds a lot. (That's the top 7 of total 116 feeds in my reader.)
