I just moderate my twitter feed on a daily basis - I create theme lists (like webdev, gaming, pixelart, reading (for these people who blog often on the topics I like) etc.) - this takes some time to discover accounts that are worth to follow, but keeps you sane from the trash info you don't want to browse.
Well blogs still exist and many of them have higher quality than few years ago because they resisted all this time, the same can be said about RSS.
Although I completely understand what you wrote. I also feel the recent boom of podcasts is also somehow replacing blogs.
