But why am I telling you all this, you ask? Well, Stikkit is gaining some pretty impressive Mac OS X integration that makes using this service a real dream. First up is a 'New Stikkit Package' created by Nik, one of their enthusiastic users (found via DF). This bundle of tools allows you to create a new Stikkit via AppleScript, your favorite app launcher like Quicksilver or LaunchBar, and even a Service (you know, Apple Menu > Services) which lets you create a Stikkit from text selected in almost any Mac OS X application. It's a pretty handy bundle that offers a lot of flexibility in how you work with Stikkit.
Another really impressive integration trick this service has is accepting drag and drop calendar events from iCal. I found this screencast on Stikkit's blog which demonstrates literally dragging an event from iCal onto a new Stikkit note in a browser, and the note collects all the info it needs like the name, date and time of the event, and even any notes you might have added in iCal. I was impressed to discover that this even works with Firefox, where traditional Mac OS X drag and drop goodness like this tends not to play.
If you've been looking for a handy online PIM to store your stuff, Stikkit is a great option, though due to its unique technology, it might take some getting used to. I urge you to check out their screencasts to get started, and then move on to cool tools like Nik's package if you catch the bug.
