You may be aware that the Internet is becoming very crowded. Google will attempt to help you get where you want to go, but is having increasing difficulties. Part of that is Google’s doing. Their methodology depends on links from other web pages, so naturally, everyone is producing web pages. Indeed, some use computer software to generate thousands of web pages to influence their Google ranking. Since Google will only use computer based algorithms, it becomes a battle of the giant computers.

Sir Tim Berners-Lee, who invented the World Wide Web, seems to be acknowledging that his protégé has problems. He has accepted one of the Knight News Challenge 2008 awards for a project that will create a technology to give users more information about the origins and sourcing of digital content. He will be working with the BBC and Reuters on what has been dubbed “source tagging“.

Tags To Bring Order To The Cyber Sphere

Tagging certainly seems to be something that has real potential in helping us all navigate our way through the World Wide Web. Tags do of course come in two flavors. You can take a body of text and use a computer to determine what are the most frequently used terms. That is one way and it may be the route that Sir Tim is following. What is much more powerful is to encourage authors to choose a few tags that they feel will best represent their work. Thankfully this version seems to be attracting more and more attention, perhaps given the problems that Google is having with computer based algorithms.

A good example of the approach can be seen in the excellent blog of Kate Trgovac. Just look at her post on links for 2008-05-13. You will find for every entry she has added tags. If you wish to see more on what she believes is important on any given tag, then you can click through on that tag. There you will find the favorites she has collected, which are typified by that tag. She is using the website, del.icio.us, to hold these favorites. That is a free service and anyone can do it.

Picturing Tags – The Tag Cloud

If you want to get a sense of what Kate Trgovac feels is important and worth tagging, how can you best do that? The del.icio.us website does give a listing of all the tags she has used (1203 in all at the moment) with the numbers of web pages for each tag. Such a long listing is a little indigestible, so a visual approach seems more appropriate. This is where the tag cloud comes in. You can see a mini-example at the top of the right sidebar. Perhaps we should mention that the tagcloud.com website is somewhat confusing here, since it seems to be only a register of RSS newsfeeds.

If you’re working with del.icio.us, it would be nice to be able to easily display a tag cloud of your favorites. Nick Bouton seems to have attempted that in 2005 but apparently ran into problems with the server capabilities of the del.icio.us website.

It is perhaps an indication of the attraction of tag clouds that a number of people have worked on appropriate software. Eric (engtech) developed one in 2007, which was somewhat complex. If you can accept complexity, then you may even be tempted to use a Flash Tag Cloud WordPress plugin that Alex Cristache found. It is one developed by Roy Tanck and is called WP Cumulus, in a pleasing play of words on the notion of a tag cloud.

WordPress Has A Tag Cloud Feature

Luckily for those who are enthusiastic about tag clouds, and are authors of WordPress blogs, the whole situation has become dramatically simpler. With the latest upgrade (version 2.5), tags are now much more effectively supported. In particular, there is now a template tag function, wp_tag_cloud. That makes the addition of a mini tag cloud to a sidebar almost child’s play. You may have noticed a small example in the right sidebar when you arrived at this blog.

Making Your Very Easy WordPress Tag Cloud Web Page

Displaying the full set of tags generated for a blog is clearly inappropriate for a sidebar display. What is much preferable is a web page displaying the full set of tags. As it turns out, with a little ingenuity there is a very simple way of creating such a web page. This is done by creating a specific page template just for that page, which we suggest should be named tags.php. A suitable code for this in the basic Kubrics theme is shown below.

<?php /*
Template Name: Tag Cloud
*/ ?>

<?php get_header(); ?>

<div id="content" class="narrowcolumn">

<?php if ( function_exists('wp_tag_cloud') ) : ?>
<div style="margin:25px;border:1px solid #111;padding:15px;">
<ul  style="margin:0 0 0 8px;padding:0;">
<?php wp_tag_cloud('smallest=8&largest=24&number=0'); ?>
</ul>
</div>
<?php endif; ?>

<p style="margin-left:33px;">
Tags:
<a href="http://technorati.com/tag/tagcloud" rel="tag">tagcloud</a>
 in Technorati |
<a href="http://del.icio.us/bwelford/tagcloud" rel="tag">tagcloud</a>
 in del.icio.us</p>
</div>

<?php get_sidebar(); ?>

<?php get_footer(); ?>

An example of the output can be seen in the tag cloud page for this blog. The only point to note is that the tags shown below the tag cloud are not a natural feature of a WordPress blog page. WordPress posts do have tags, but WordPress pages do not, unless they are added manually as is done here. The left-hand tagcloud tag for Technorati is applicable to all tag clouds and can be left as is. The right-hand link for the del.icio.us tagcloud can be modified to link to the individual author’s del.icio.us tagcloud favorites, if so desired.

You can copy and paste the above code to create your own tags.php file and it can be FTP-ed to your own Theme folder. The properties of this file should be set to Read and Write for the Owner and Read only for others.

Once the tags.php file has been uploaded, the Tag Cloud web page is very easily created as a New Page in the ‘Write Page’ Subpanel. Select the template to be used at the very bottom of the Subpanel from the drop-down list. Its name is Tag Cloud. In the Title field, type a suitable Title such as ‘Tag Cloud for this Blog’. Within the Content field, type the text which should appear as the heading within the Page and this is all that is required. This could appear as follows:

<h2>Tag Cloud for this Blog</h2>

The template will then automatically add in the complete tag cloud together with the two tag links for tagcloud which appear below it.

Once the Tag Cloud Web Page has been created, a link to it can then be displayed at an appropriate point on the Home Page. Visitors to the blog can then easily use it to get a sense of what subjects the blog covers.
