thanks – yeah, I’ve been doing it via multiple loops / categories for a few years – I think the tags would be easier for a noob user. Also using categories confuses the use of categories as a concept, whereas using tags keeps the <placement on the page>, and the <categorization of posts within the site> separate from a usability standpoint. (we’re building wp-cms for clients)
I also find moving the blogs using the categories can sometimes be a pain.
I just can’t find any documentation on WP Codex about using tags in the loops, perhaps I’m missing something?
