This, of course, was taken completely from my brain
It is correct that any data listed on the Main Page and in the Search Results view will not directly generate a “hit” to its parent site unless a reader clicks through. In Beta 2 the main page view only displays snippets, not full articles and will hi-light search terms in context. The reason this was not the case in the first Beta is that WordPress’ summary function was clunky and tended to slow things down. This is no longer a problem with the new software, which I have complete control over.
There will also be a means for authors to change the size of the snippets to suit their preferences, where the default length (for both posts *and* comments) will be roughly 200 words.
On the individual page view, no content that is displayed (other than the navigation bar) is from the Reference Library servers. The content is loaded directly from the author’s site to the user’s browser via an iframe, which not only generates a “hit”, but also registers with Alexa, Google, and other search services as an incoming link, thereby *boosting* page rankings.
