When you concatenate a buffer with a string, you get a string as a result - pretty much the way you get a string when you concatenate a number with a string.
The point of the "BODY " + chunk was (at least i think so) to show that you do actually get multiple chunks, which wouldn't be as obvious if you'd just console.log all the chunks after each other.

res.on('data', function(chunk){
console.log('BODY:', chunk.toString('utf8');
});

var request = http.get('http://teamtreehouse.com/'+username+'.json',function(res){
res.on('data', function(chunk){
console.log(chunk); // <Buffer 7b 22 6e 61 6d 65 22 3a...
console.log('BODY:' + chunk); // string
});
});
