I saw the promo video of Skitch some time ago, but then I really didn't imagine how great it is to actually use it. It's super fast, very easy to use (I love the fact that you get subtle, not intrusive, and useful help tips just when you need them), and it works like magic (even though it's still a beta). The app was created by plasq, the makers of Comic Life (another application I love to use!), and I can only hope that we all get a copy of Skitch in the next releases of Mac OS X (just like we get the basic version of Comic Life).
I really see myself using this application a lot for different purposes. One obvious use is surely making images for blogs, and I think it will also be great for making annotated screenshots for user manuals (which can be really time consuming!), sharing ideas fast or just having fun by adding captures to photos :) Skitch is surely a great product that wisely uses simplicity and provides with all the tools you need to make photo sharing a bit more fun and fast. I think I'll keep the Skitch icon (it's a cute pink heart :) ) in my dock from now on, just in case I need to skitch something fast (it's surely much faster than Photoshop for simple tasks Skitch was built for).
If you want to know more about Skitch, take a look at plasq's site and watch the Skitch introductory video, which is in my opinion a great example of how to make an attractive video manual for first time users (I usually give up on video manuals after a few seconds, but this one kept me interested).
Edit: Just got 100 invites to give out! Leave you e-mail under the comments or e-mail me at ialja (at) mac (dot) com to get an invite and to try out the Skitch magic :)
