I think the better question is...
Among the handful of MNS sellers in BHW, are there any good ones which can deliver sites that have real potential of making money?
Again, if it was so easy, everyone would be doing it. That's the reason why people think it's "dead"... It's cause ranking MNS are not as easy as before. But if you get a good site and you rank it the right way, you will see results.
This is something I personally want to revisit again sometime this year. I had a few failed MNS ventures a few years ago. It will be nice to see if I can profit this time around.
