To look at Eric T. Schneiderman, the Attorney General of New York, you wouldn't think he's a hip HOP guy. And, in fact, he's just a modest bureaucrat who has embraced the acronyms of his occupation with enthusiasm.
HOP stands for Home Owner Protection.
MAP stands for Mortgage Adjustment Program.
And the APP is something you can use on your desktop or smart phone to find out whether the enterprises offering "help" are legit. Many are not and Schneiderman looks downright gleeful when he talks about shutting them down.
