I'm fairly certain Google Reader shutting down won't affect blogger, except for those who are reading blogs through Google Reader directly. People who read your blog through the "Liity tähän sivustoon" option shouldn't be affected in any way. A bit more discussion here (in Finnish):http://satiinitaivas.blogspot.fi/2013/03/bloglovin.html
Good to know.
I didn't knew about it! I've just registered on BlogLovin alredy ;)
