I would say RSS is still my primary tool for reading new content, but email is becoming a close second. This is due to a couple of excellent newsletters I receive each week. These newsletters are similar to this one you're reading, in that they each contain links to multiple articles that may catch my attention.
If you haven’t already, check out each of these
While RSS is still a reliable, convenient way to get new content, these newsletters are a slightly better method to send a curated list of content. So while I subscribe to more RSS feeds, each feed may result in 1 or 2 articles of interest over a week. But these newsletters can refer to 3–5 articles each week that may catch my interest.
I look forward to them every week.
