As suggested by Amit, I thought I'd drop a note about Labelr and <a
href="http://ghill.customer.netspace.net.au/freshtags">FreshTags</a>.
John at <a href="http://blogfresh.blogspot.com">Freshblog</a> wrote a
<a
href="http://blogfresh.blogspot.com/2006/02/new-category-service.html">review
of Labelr</a>. I followed up with a crude analysis of what's going on
under the hood (check the comments).
I suggested some avenues to explore for integrating Labelr with social
tagging services (like <a href="http://del.icio.us">delicious</a> and
<a href="http://technorati.com">technorati</a>). Apart from visibility
and category/tag management, doing so would also allow Labelr users to
take advantage of FreshTags for flexible presentation of tags and post
titles. It would also support other "social aspects" of tagging, such
as readers passing tags between blogs and blogs picking up tags out
search engine queries. (Read this review of <a
href="http://blogfresh.blogspot.com/2006/01/freshtags-v-05.html">FreshTags
blog navigation and integration</a>.)
In terms of technology, both FreshTags and Labelr require a Javascript
object with tags and posts stuffed in it; FreshTags gets its as a JSON
feed from delicious. Worth looking into?
Cheers,
