I hope this is the proper place to post this question. And I hope it hasn't been covered elsewhere. I tried many variations of a search and did not find this particular question. Maybe its so obvious to skilled users it isn't necessary. In that case I apologize.
As a CMS I am finding WP3.0+ to be very good but of course it is still maturing in this role. For my usage its Achilles heel is the sharing of content amongst a related group of blogs/sub-domains. NextGen Galleries works pretty well for pics.
I would like a post from one blog to be displayed in the post of a different blog. This is simaler to the way external pics are grabbed and displayed. Even that though creates a new page permalink which looks like duplicate content. I would like to reuse the originating post link within the second blogs structure. Primarily I want to avoid upsetting Google analytics search for original content, not repeated content duplicated between blogs.
Of course I can copy/past or export/import or create external link which jumps out of the current blog back to the originating blogs site and post.
Thanks and my apologies if this turns out to be a completely simple and lame query.
