When someone has an opinion like this one should wonder if they ever used RSS. Web applications for RSS aggregation is worse than using IRC in a web interface. I cant take strong opinions about IRC seriously either if the person didn't install a client. With RSS the person is merely describing himself.
Please do go install [or make] a client, gather some feeds, do some filtering. When you have your first 10 000 subscriptions I'd love to hear every angle of your story, the topics, the organization, what client you use, what language it was written in, what database it uses, who wrote it. ETC ETC
The walled gardens full of [self] censorship, data mining, adware and bullshit content have useful features too! Aggregation isn't it. HN headlines only vaguely map to our interest but reading the comments is wonderful.
(Reminds me to install thunderbird and backup my gmail. I'm not young enough to trivialize losing my data.)
