I’ve known for some time that [version 2.3 of WordPress](http://codex.wordpress.org/Version_2.3) would support real tagging. Today, Matt has just announced the [deployment of tagging on WordPress.com](http://wordpress.com/blog/2007/09/22/tags-and-categories/).
From the start, I’ve been a very vocal supporter of the [differentiation between tags and categories](http://climbtothestars.org/archives/2006/02/11/tags-and-categories-are-not-the-same/) — and I really appreciate Matt acknowledging this in his announcement.
When I first met Matt offline for the first time nearly a year ago, [at Blogtalk Reloaded in Vienna](http://flickr.com/photos/bunny/sets/72157600218664445/), I jumped on the occasion to pester him about tags and categories. He listened — but I don’t think he was convinced at the time.
A few months later, I was [in San Francisco](http://flickr.com/photos/bunny/sets/72157594465240661/) — and one of the first things Matt told me when we met again was “you know, I finally saw the light about tags and categories”. He told me version 2.3 would have both. I was overjoyed. I’ll never know exactly what role I played in Matt’s “seeing the light”, but I like to think I contributed 🙂
Looking back in time, [Technorati started indexing tags in January 2005](http://climbtothestars.org/archives/2005/01/14/technorati-tagified/). They weren’t new for me then (I’d been tagging things on del.icio.us since May 2004 and on Flickr since October of the same year) but clearly, being able to tag posts was a great thing. You know me — my brain can’t sit still — two days later, I was [rambling about some ways to combine tags in searches/sorting](http://climbtothestars.org/archives/2005/01/16/thinking-about-tags/). Some of the stuff I talk about in there isn’t possible yet, but I hope it will someday.
Two days after that, I wrote my first WordPress plugin, [Bunny’s Technorati Tags](http://climbtothestars.org/archives/2005/01/18/technorati-tags-plugin/) — which became quite popular and which I still use to this day.
I’m really glad to be able to retire this plugin, specially as [Peter Westwood has written an importer for it](http://blog.ftwr.co.uk/archives/2007/09/07/living-on-the-edge/). That means you should have no problems converting your bunny-tags into wp-tags. Thank you very much, Peter.
Bear with me while I dig though my archives: [weighted tags by category](http://climbtothestars.org/archives/2005/01/28/plugin-idea-weighted-tags-by-category/) is something I’d forgotten I’d wanted… does anything like that exist now?
My only gripe with the implementation of tags in WordPress, for the moment, is that they will be comma-separated. No! Please! We’ve been typing space-separated tags into Flickr and del.icio.us for three years now. Three years! When I chose space-separation for the tags in my plugin, it was because the existing interfaces for tags did it like that.
Spaces, please. Or at least an option to input them space-separated. Or a simple plugin. Tags separated by spaces, and multi-word tags between quotes.
