There are literally thousands of modules available on Drupal.org. The funny thing is, most developers tend to use only a small percentage of those modules. So out of 16,000+ modules, many developers have only installed up to 200 different modules across their various projects. Furthermore, I think you will find that developers continually use only a few dozen of the same modules on almost every project. It's for that reason why from time to time I like to put together a list of my most-used modules. By doing so, I hope to help new developers figure out what modules they need by narrowing down a list of 16,000 down to around 50 or so modules.
Late last year I released my first top Drupal 7 modules which superseded my original Drupal 6 top modules list. After looking at feedback from my first D7 list, now 6 months later I wanted to give a refresh. As you will see, some new modules have been added to my favorites list while others have slipped in the rankings. This is certainly a subjective list. I am not trying to list the best modules or the newest hot modules out there, this list is all about my most used modules. This to means that if you are a Drupal newbie, you should have these on their radar.
NOTE: that I have tried to indicate on the list where I have made changes. You will see several 'New' and 'Updated' labels. 'New' does not mean new to Drupal, but rather new to the list.
I think this is a really good list for newbies to get started with, but I would love for your feedback. Thanks and enjoy!
