I can’t stand seeing blogs that have a long list of monthly archives in their sidebars (I’m looking at you, prefab Blogger templates!). It clutters the design, and promotes long sidebars.
Blogger users, unfortunately, don’t have the nifty Pages feature WordPress bloggers get (or plugins for that matter), so they won’t be able to enjoy this amazing WordPress plugin.
Smarter Archives, creates a new template tag,
<?php wp_smart_archives(); ?>, that you can put in a custom template, allowing you to build a custom Archives page. I use it here, and ProBlogger does also.
The plugin displays the monthly archives compactly, one line of text per year, so you have room on the page for other things, like a tagcloud, output from the Popularity Contest plugin, etc.
