I don't think this is a bad idea. Let other's aggregate what's important and filters up to the top. I'm the same way. I used to subscribe to a lot of blogs and stuff, now I just visit Hacker News and my custom Reddit front page, and read a couple articles that are popular, and then get on with my day.
If you find yourself staring at the URL bar with nothing to do because you already visited your curated aggregation site, maybe you don't need to be randomly surfing the Internet, and instead can accomplish some important work. (This is a good place to be in as opposed to someone hot-tabbing to 10 different websites.)
I used to feel this way but there is intellectual concentration risk. Reading the same stuff as everyone else has created an echo chamber for me, and I intend to seek diverse sources again like I did before the link aggregator era.
