I love reading your site and Lifehacker.com. They have a tag based system for which feeds you can subscribe to, see here. What can I do to similarly get the digest version of your best posts?
Actually WordPress automatically generates feed for different categories. This means each of MUO categories or tags has its own feed.
Unfortunately we don't provide RSS feeds for different parts of the site, nor do we do a "digest" feed. All we have is the main feed - http://feedproxy.google.com/Makeuseof
What you could do is subscribe only to the MUO writers that interest you. Each MUO writer has their own RSS feed and you can find them by going to the MUO front page and in the sidebar are a list of everyone that works for us. Click on the name of the person that interests you and you will be taken to that person's author page. For example, here is mine - http://www.makeuseof.com/tag/author/mark
Now at the top of the author page, click on "MUO Author Feed" and that will take you to your favourite RSS reader so you can subscribe.
Unfortunately that is all we can offer you right now.
