Not sure what Quicksilver is? It’s a luncher, a search tool, a shortcut tool, a butler, a maid, and a kitchen sink. It’s everything! And every day I read about people who have created yet another plugin to further enhance the program.

But if you’re new to Quicksilver, or want to just see what all the fuss is about, then check out the two screencasts that my friends over at TheAppleBlog cooked up. These videos for beginners will introduce you to the wonderful world of Quicksilver. And I promise you, once you’ve seen Quicksilver… you’ll never go back!

Because I’m never at the same client location for very long, my web proxy settings are always changing and I never have very good luck running AIM behind the myriad of different firewalls. Enter Meebo.

Meebo is different from other messaging apps because it’s completely web-based. Simply login to Meebo.com and a web-based instant-messenger appears that you can then pop out of the window to behave just like any other messaging client. And, if you have multiple IM accounts, you can sign up for a Meebo account (free) and then login to AIM, Yahoo, MSN, ICQ, Jabber, and Google Talk all at the same time! This concept isn’t new, but the way Meebo has allowed anyone to login to their favorite messaging client (or all of them) form anywhere in the world with an internet connection is just brilliant!

Oh, and I almost forgot! If you’re worried about security, or your company’s local IT guy spying on your conversations, simply login to https://www.meebo.com (the extra ’s’ stands for “secure”) and you’ll be connected to a secure version of the client which keeps your conversation on the Meebo server instead of yours. Simply brilliant!
