Currently, there is an incomplete related content modules comparison in the Organizing content with taxonomy section. There needs to be a broader comparison added here that cover modules that do not just focus on taxonomy.
The discussion of similar content recommendation modules is happening at on the Taxonomy Drupal group.
TODO: migrate over modules into a comparison table
TBD: how to handle the table since it will be very wide... perhaps create categories?

Check out the Featured Content module to create featured and related content blocks. Here's the project summary.
The Featured Content module lets you very easily create related/featured content blocks on your Drupal site. This module is useful if you have non-technical users who need to add blocks on the site that contain lists of node titles, node teasers, and/or full node content. This module can also be useful if you need to get up some related/featured content blocks quickly and are not familiar enough with views to do it, or simply prefer not to use views for this purpose. A related/featured content block can be created in just a few minutes.
There is much more info available on the Featured Content module project page.
TODO: Even though it is very easy to use, it might be nice to have a quick tutorial for some of the most common use cases.
Similar / Relevant by term is based on the taxonomy terms assigned to content. Blocks are available based on similarity within each of the defined vocabularies for a site as well as a block for similarity within all vocabulariesRead more
