The multisite implementation I am trying to develop is rather complex (I believe it is). It will be aggregating content from a global community of sites with a common interest. I will be attempting to pull posts from sites with a streaming gallery on the landing page and drill down to specifics based on inquiry of historical time frame, topic of interest, and/or location.
I have set up a series of tags that refer to those general topics. I am then planning to use the theme template plug-in to replicate tags for the use of the site holders, the site holders will have some locally or topic specific categories.
Question 1. I was told that I should plan to have limited categories but as many tags as I want. Any comments or suggestions?
Question 2. From the main site, I would like to stream site posts across a gallery and then have the ability to search for specifics based on tags. what should I plan for when pulling posts from the various sites.
Question 3: Any comments on architecture from a performance standpoint? It will be image intensive.
