do me a favor.. Only recommend things with one account. If you start using both accounts to recommend things, it's going to be very hard to make a good argument why people not should do the same thing to game the front page.

One man, one vote!

You're contending that a stream is equivalent to an identity. That is an artificial constraint, and it is going to break down sooner or later.

The purpose of having two streams is to apply a filter; it goes with that definition that items will be multiply recommended.

As far as "gaming" the front page goes, it's hardly necessary to recommend things twice. Take a look at the front page any time in the last week, and you'll find at least half of the entries are from the pnw stream. Most of those are not recommended by anyone else. There have been many otherwise "slow" periods during which the entire front page is essentially a subset of the pnw stream.
