Mail on HabraHabré

From time to time, reading topics, I want to leave the author a comment. For example, about a grammatical error, to express your thoughts, suggestions, ask for an invite, suggest where you can get the material for a more complete coverage of the raised topic. All these things are wiser to make personal messages, which, unfortunately, are not implemented in the most successful way.

As you know, you can write messages only to your "friends", so you have to add almost all horrible. And if I basically do not want to have friends?
We have to make an application for adding friends, and already indicate in it your own and ideas. Agree - uncomfortable? Why not modify the private messaging system? Then comments to the topics will be much cleaner. ;)
