A lot of us have been responding to old blog posts that are several years old. So just a head's up: TAKE A LOOK AT THE CREATION DATE at the top of the blog to see when it was written before you respond. You might be responding to someone who has long since left the site. Worse, you might be worrying about the person's strife at the time they wrote the post and it has long since passed.
The information they're presenting may be interesting and have an impact on your quit, but just LOOK before you post a response.
