$15 a month per subscriber; surely one person can write hundreds of messages and maintain dozens of personalities a month, especially when aided by some text recognition and pointers (&quot;your personality with this customer is &#x27;nerdy&#x27;, suggested replies: &#x27;Dr. Who is the shit!&#x27;, &#x27;ia! ia!&#x27;, &#x27;bush did 9&#x2F;11&#x27;&quot;). I don&#x27;t know what the average income in the US is, but with a hundred subscribers per person you&#x27;d be looking at about $1500 &#x2F; month, which sounds decent.<p>It also depends on how much messages you get though; I&#x27;m sure there&#x27;s a few that will just chat all day to fill up a need for social contact, while others will just message a few times a month to keep up appearances. Of course, as &#x27;girlfriend&#x27; you could (and probably should) do some flood control yourself (max x messages &#x2F; day &#x2F; person) to be able to keep up with as many clients as possible.
