Impressive Rated 5 out of 5 stars
As a programmer, I have to admit this add-on is awesome. I used to use Google Reader, which will shut down on July 1st. I started to look for a replacement and came across Brief. Not only is Brief similar to Google Reader, but it also has other useful features: offline reading, customizable folders etc. Also, it is light and easy to use. Congratulations Adam, and keep up the good work!
PS: I can't believe some people (a minority, actually) rated this add-on 1-star or 2-stars. You guys should be ashamed of yourselves. The developer has worked for you and FOR FREE.
