Donncha’s just released a brilliant plugin that’ll make a heck of a lot of people happy, site-wide tagging for WPMU.
Here’s the run down:
This is the initial release of a plugin that creates a set of pages like the WordPress.com Hot Topics pages. It’s a lot more simplistic, but by feeding posts into one blog it also creates a sitewide feed of all posts plus feeds of any tags and categories too.
I can’t tell you how happy this would have made me as a new user back in the day, it’s one of those ‘ultimate’ features whereby you suddenly get to connect all blogs in one place, people can see what’s going down in different places and (at least I hoped) would hook up with each other.
Which interestingly enough never really happened – even on a service that was originally geared entirely towards teachers, a serious common interest group, there just wasn’t that much connection going on and sitewide tags did nothing to help that.
What they did rock out at though was:
- Allowing people to get a good feel of the kind of things people were using the site for
- Allowing people to ‘feel’ like they are getting attention
- Building SE traffic! (I *think* although I could well be wrong here, that tags pages account for definitely double digits % in terms of wp.com traffic despite having no actual ‘original’ content on them)
Which, all put together make for a darn useful plugin!

You know what would go great with this post? Screen shots of what readers would see! But it is a cool concept.
There’s one her so far: http://ocaoimh.ie/wordpress-mu-sitewide-tags/ But I’m sure they’ll be more, Donncha’s usually really iterative with his work.
Oh, man. all that tinkering to get my little avatar plugin with work with my current tag plugin, wasted! i guess its good that I was planning on moving to your avatar plugin anyways and this tagging option is way cleaner than mine.
sweet!
I know what you mean! Although I try to be philosophical about it… y’know, kinda like ‘well, I must have learned tons in the process’ :D
I got my posts to display on the new blog by toggling the publication status of the posts on the other blogs. Awesome. Go-Go-Uber-Blog!
Um, I don’t *toe-scraping* see the pages that are created… Plus, I kind of see where this is going but I don’t quite see how to get there *cough* With this, I’d be able to publish RSS feeds for each tag on the uber-blog using template tags, yes? I’d be able to feed a tag-specific sub-blog with aforementioned feed, yes along the lines of mouthbreather.blogdomain.tld using a wp-o-matic type of plugin, yes?
Flame away!
Thanks.
well I can only agree with village idiot – I see what this plugin offers still I lack the imagination to come up with possible ideas for its use…
maybe someone can give some examples they used this plugin for?
Hello!
