What I found from using this product in the past few weeks is that it helped me re-engage with the people I missed their tweets, either by replying or clicking through the links. Twitter also has the dailiy / weekly digest functions, but it's organized by most popular tweets (https://twitter.com/settings/notifications https://twitter.com/settings/notifications). Sometimes I just want to know what my cousin back home or an ex-colleague tweeted about, which is useful for. One thing I'd like to see is to make more than one list, or be able to set email digest for some of my existing lists.
