The first line of the first Google hit for your company says: "...JobMob is about bringing together job seekers and jobfinders ..."
Unfortunately, to me, neither one nor two comment bubbles conveys, or even vaguely hints at the above intent. To me, two comment bubbles, even if pointed towards each other, only suggests two separate comments, not conversations between job seekers and job finders.
On your website, you also comment that the "conversations" are "within the mob". No matter whether I am an employer or a job seeker, I wouldn't care in the least about conversations "within the mob". I would only care about conversations with people in the opposite group. IMHO, since presumably that is the main function of your organization, and is likely why most people sign up with you, you need to convey that much more clearly in your logo.
Although you may not want to depart too far from your previous logo design, you may need to change more than a few relatively superficial visual aspects. For example, if "the mob" refers to the mob of job seekers on the market, how about separating the words with something like a nice graphic two way arrow between them, eg, Job <--> Mob , as your logo?
Just my $0.01,
