You do know you can unsubscribe to the main page, and the other default subscriptions, so your main page is entirely business, world news, programming, and Doctor Who, right?
There are great subreddits that are worth checking: askscience, personalfinance, frugal, programming, and lots of that fit your interests with lower signal-to-noise ratio than the main page and the default ones.
Frankly, it's too much work to find the good ones.
