If that works for you, then cheers. I get so sucked into Reddit's front page that I just need to avoid it all entirely. With Twitter, I'm less inclined to explore.
If you don't do this then it's like you bought a TV that was programmed to only show you the most popular channels. And then you never manually changed the channel yourself.
So, sure, that would obviously suck. You have to change the channel.
The Reddit front page is simply reddit.com. It shows the most upvoted content from all the subreddits you are subscribed to. Alternatively the most popular ones from the standard subreddits if you don't have an account.
