What is the Feedspot?

Hi!
Some weeks ago I got some e-mail of "founder of Feedspot". According of that message I have got some followers by that site. Now I would like to find out what is that mysterious Feedspot and make sure that wasn't only trash I ask you my follower some favour.

If you are following my blog by the Feedspot report yourself and tell me how did you find my blog, why you are following this and what is your interests about my blog?
:)
Thanks <3
