For example, it would be nice if Spotify offered something similar to Netflix's experiments with multi-user profiles for single accounts. In addition to recommendations geared towards me, such as Daft Punk, The White Stripes, and Macklemore, my Discover feed also featured recommendations for artists popular with Raffi fans—one my two year-old son's favorite artists.
In general, the recommendations seem more focused on your recent listening habits than your entire Spotify history. My editor's Discover feed was filled with hip-hop recommendations thanks to a classic rap binge despite the fact that he historically tends to listen to a mix of rock and electronic music.
There's also no obvious way to share items in your Discover feed with friends in the Web app. The desktop version lets you click through to individual artist/playlist pages and share those normally, though you can't share news, reviews, and concert listings from Spotify's partners.
All-in-all, though, Discover is a vast improvement to Spotify's core service. I can definitely see myself spending a lot of time using it to plumb the depths of Spotify's music catalog.
