I look at Inoreader to catch up on my RSS feeds during the week and I will star items I'd like to read more about later. If I'm lucky I get to look at the starred items once a week. Almost everything I'm interested in has an RSS feed. Hackernews goes into the feed reader as well.

I keep my personal email open and glance at it a few times a day to make sure there's nothing super important. I also clean up my email about once a week.
