Thanks for the great info! Some of those modules will definitely appeal to more experienced users, or only those wanting some specific functionality – but the one-sentence overviews are excellent for helping any user quickly determine whether or not to further investigate some item. I wish every module came with that sort of one-sentence summary; alas, the actual overviews that come with modules vary widely in length and comprehensibility.
You're right that a setting up a site from scratch can take a long time; a fresh Drupal installation is best described as "bare-bones". (Which is actually a good thing about Drupal, of course – no unwanted cruft!) Like (I assume) many users, I've created my own "sandbox" Drupal setup that I can clone for any new site, pre-configured with all the modules and settings that I'll probably want to use. Some further detail on that sandbox would be a good follow-up article to this article.
