[Warn: a bit promotional]
I'd like to have your opinion on Theneeds [1]. It can't be compared to Medium as we're not for blogging, but we do a lot of personalization/recommendation.
At signup you select your interests and we build personalized streams of curated content mixed with user generated one. Then, we learn from your activity to get smarted about what really matters to you.
Moreover, we have a newsletter (default daily, but you can change the frequency) where we recommend you 8 news across your interests.
