Attention all ye users of Adium, Skype, iChat, Twitter, Facebook and Jaiku - Brett Terpstra has struck again with MoodSwing, his excellent utility for updating your status across all these apps and services. Why do I call it a utility instead of just a Quicksilver action, you ask? Because Brett is now providing both the original action and a new full-blown menubar app - at the request of TUAW readers - called MoodBlast. Both now live on the same download page at Brett's Circle Six Design blog, and they both allow you to update your status across all the aforementioned services at once. While MoodSwing is an action you set-and-forget to work with Quicksilver (though you can reconfigure later), an advantage of the MoodBlast menubar app is that you're presented with the UI you see above every time you activate it, with any services you used previously already selected for updating. The other advantage of the MoodBlast app, of course, is that you don't need Quicksilver in order to minimize the effort spent for online socialization.

As with his other excellent projects, Brett Terpstra provides MoodSwing and MoodBlast as donationware.

If it seems like it was only last week that Brett Terpstra introduced his side project MoodSwing, a clever script that allows users to change their status message across multiple apps with Quicksilver - well, it was. People loved it, so Brett quickly began updating, tweaking and adding a slew of new features and services that MoodSwing could manipulate. The script is now up to v4 with a dedicated page at Brett's Circle Six Design blog, listing out all the features and supported services:

• Supports Adium, iChat and Skype
  
• Supports Twitter, Jaiku and Facebook
  
• Automatic Qurling of long URLs
• Word Count
  
• Send current weather (international)
  
• Send current iTunes track
  
• Encryption of passwords stored in preferences
  
• Easy-to-edit defaults, can be overridden by command syntax

In a surprisingly short time, MoodSwing has become an incredibly powerful Quicksilver action that can simplify the process of letting your friends across many services know what you're up to. The action is pretty easy to set up and configure to your bidding, but be sure to check out the MoodSwing page for instructions to get the ball rolling. As with so many of Brett's other excellent offerings, MoodSwing is provided as donationware, so scroll down on Brett's Downloads page and show him some appreciation.

We've definitely caught the Twitter wave here at TUAW (we even have our own account), but it is by no means the only 'what are you doing' or lifestream service on the block. Another big player is Jaiku, which brings a fairly different perspective and set of features to the table. While Twitter focuses primarily on asking 'what are you doing?' and offers straight text input, Jaiku allows you to add RSS feeds from virtually any other blogs, sites or communities you post content, generating a sort of play-by-play for almost everything you're creating on the web. This definitely swings Jaiku over to the lifestream category, and it has a number of other features that will likely appeal to those who are looking for more than a plain text mini-blog, such as 'channels' that allow Jaiku users to all post in one theme-specific area (likening it to a giant chat room), as well as an actual comment system on posts.

A major boost for web services like Jaiku (where we also have an account), in my opinion, is great software that can hook into them. While using a browser to interact with these services is fun and all, nothing beats the speed, flexibility and (ideally) extensibility of a well-written desktop client, and Juhu for Jaiku is exactly what I'm talking about. Doing for Jaiku what Twitterrific does for Twitter, Juhu is an app that lives in the menubar, giving you a resizable window for peeking in on what your Jaiku contacts are posting. Posts, RSS links and channel chatter are all available in Juhu's nice, compact UI, as are some of the nice little touches Jaiku offers, such as adding an icon to your posts and specifying your location.

All in all, Juhu is a great client for a feature-packed service that's been progressing very nicely. Fortunately, just like Jaiku, Juhu is provided free and is also open source under the MIT license. If you've been looking for a different take on the lifestream service, Juhu makes Jaiku a great option for Mac OS X users.
