I've been happy with Newsblur.com: the UI has a number of improvements over Google Reader — especially the trainer which allows you to prioritize keywords, domains, authors, tags, etc. up or down (great if you follow people who share things on multiple topics and you're just not interested in one of their hobbies) and the option to have it automatically load the remote article text, which is configurable per-site — perfect for sites which only publish a snippet of the full article. The social features are decent but definitely show the market fragmentation since the number of users is so much smaller than when almost everyone was on Google Reader.

Beyond the technical aspects, there are two things which I really like about Newsblur:
1. A non-bubble business model: it's a lean but reportedly profitable service, which means you're not looking to move as soon as the venture capital runs out
2. It's all open-source: https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fgithub.com%2Fsamuelclay%2F... has the entire site and the official Android and iOS clients
