[wp-hackers] Status of sitewide categories/terms in WP3

[Bjorn Wijers]

After giving it some consideration I have decided against using sitewide 
categories. The current state and future of the sitewide categories at 
this moment does not look too bright. Since I'm under time pressure to 
deliver the requested functionality I have decided to rewrite my plugin 
to work independently from the WP core for aggregating posts from 
multiple blogs in one WP install.

For those interested in aggregating posts from multiple blogs in a WP 
multisite install: I will publish my plugin in the wp repository under 
the bbAggregate when the first version is finished.
