Screenshot sharers should shout in celebration, though they shouldn’t try saying that three times fast. Skitch has been bumped to version 1.0.4, and its most notable new feature is that it no longer requires that you create a skitch.com account in order to use the software. Other improvements include a simplified Welcome screen, and a fix for a crash affecting some 10.6.6 users. (Free, 6.5 MB)
Mac OS X Zip Expanding Utility
Firefox (and possibly other applications) may ask you what you want to do with .zip archives that you download from the Internet. If you want to expand them with Mac OS X (rather than StuffIt Expander), you may be unsure of which application actually does the job. You're looking for Archive Utility (in Leopard and later) or BOMArchiveHelper (in Tiger). In either case, the application is stored in Hard Drive/System/Library/Core Services/. Don't move it from there, though, or you'll confuse matters.
