Okay, not the best icon and an even worse logo, but who cares! Growl for OS X is just about the most useful app on the planet! As usual, I am a late comer to “the coolest apps” party but I have a good reason this time (or at least I think I do anyway). I knew about growl, but didn’t really have a complete need for it until today. Twitterrific 2.1 beta was released today and it incorporates Growl for tweets. Now if this isn’t the most important use for growl, I don’t know what is! Admittedly, I think I may be caught up in my recent double app install excitement, but I do think that growl has to be really high on my “Essential Apps” list after the events of the day today. That said, I highly recommend Growl for your Mac and wish you the best.

One note of advice: you will probably have to reboot after installing and configuring Growl for the first time. It didn’t pick up my Growl friendly apps until I rebooted (FYI).
