PS, to recap: in the first case above, some interesting posts will be 
missed by one of the planets from time to time.

In the second case, enthusiasts who follow both planets (eg in google 
reader, like me) will see duplicated posts fairly often.

I guess I'll propose, then, if you are a blogspot author posting on both 
general squeak and croquet topics, please consider enabling and using the 
topic tags ("Labels") feature. (And any equivalent if you use some other 
blog software).

You may need to upgrade to the newer version of blogspot, which is a good 
idea in any case. Then you can tag some posts with "croquet", some with 
"squeak", some with both - and the planets can subscribe to 
".../search/label/squeak" and ".../search/label/croquet". You get the idea. 
I know it's a bit more hassle when you just want to blog, but it seems like 
the best way to deliver the content people want to see. Comments and 
alternatives welcome.
