Actually, that was the reason I hesitated doing something like this for so long.

But I don't see any reason why I can't separate my posts between two journals and have it work seamlessly.

And I had another thought. I feel strongly that participation in my life to any extent should be entirely voluntary -- IOW I am not going to demand that people be interested in every aspect of my intellectual life in order to be my friend or associate.

I'll give it a few weeks, and we'll see if either journal becomes shallow or dry; in which case I'll re-assess this solution.
