Three Essential Drupal Modules

I just want to make a quick mention of three Drupal modules that I find absolutely indispensable for any web project:

Pathauto

"The pathauto module automatically generates path aliases for various kinds of content (nodes, categories, users) when no explicit alias is provided by the user."

Poormanscron

"A module which runs the Drupal cron operations without needing the cron application.

For every page view, this module checks to see if the last cron run was more than 1 hour ago (this period is configurable). If so, the cron hooks are executed, and Drupal is happy. These cron hooks fire after all HTML is returned to the browser, so the user who kicks off the cron jobs should not notice any delay."

Tagadelic

"Tagadelic is a small module, without any databases, or configuration, that generates a page with weighted tags. The cool thing is that by merely altering font sizes, these lists suddenly gain a dimension.

Tagadelic offers various ways to add terms and vocabularies in one tag cloud. By using the urls, you can create your own clouds pages.

It also offers a sideblock for each taxonomy tree."

I find these three modules necessary and very helpful. I use all three of them for this site, as well as almost all of the other Drupal sites I have worked on.
