Another awesome interface, Hello Cotton is easy to navigate. I've never used it but I've heard great things.
Also have heard good things about feedly. An option for those who like actual list formats.
So, there are a few options for you bloggers out there. I have been using Bloglovin on and off for a few years now, and it has improved quite a bit. Its respective iPhone and Android apps work well too! Can't speak for the other platforms but I'm sure developers are busy right now perfecting with GR on its way out.
If you're interested in keeping up with my blog, I have Bloglovin linked on the right hand side. Thank you for following, I look forward to everyone's posts on there. Good luck! x
