If you still qualify a magazine that's made available for general download from a public web site, as 'secret', this is only proof that JW's don't have the monopoly on stupid people!

Seriously, back to the original thread topic, there is NO Secret Watchtower. As you mention, it's now available free to the public on the WT website and they don't even have to step foot in a Kingdom Hall.
Are the two Watchtowers targeted at two separate audiences? Absolutely, as would make sense.
Personally, I found the "old" Watchtower generally difficult to offer to the public. I think most of us here that have done magazine work on a Saturday have usually featured the Awake instead of the Watchtower. I generally centered my presentation around the Awake since it tended to be "softer" and often more related to current events or issues that people could more easily relate to.
Trying to offer the old Watchtower to the public that featured some article about a prophecy from Habbakkuk Chapter 2 or Zephaniah Chapter 3 was crazy. First, most people have never read the Bible and trying to make some relevence to a prophet they had never heard of to 19th/20th/21st century events was just too much. Now that I think about it, I bet I presented the Awake articles 4 out of 5 times more than a Watchtower article.
So yes, without question, the two new Watchtowers have different purposes. Plus, by doing it this way, they save a LOT of money.
