Seesmic, the free Twitter/Facebook app, received a major update today. Watch out! With all these new features, it's only a matter of time before the app outgrows its human oppressors.

Seesmic version 1.5 changelog:

Improved user experience: We worked hard to improve the user experience with the context menus, and we hope you'll agree that the experience is slicker than ever before.
Saleforce Chatter: We improved the UI to make navigation more intuitive.
Speak a tweet: Yes, tweets read outloud to you! We are not kidding!
Trend integration: Check out "What The Trend".
SMS Integration: Send a tweet via SMS.
Hyperlinks: You choose how you would like to open hyperlinks, either in-app browser or Internet Explorer.
Spring cleaning: Yes, we got rid of a few pesky issues in Facebook timelines and complications with Twitter logins.

The Speak a tweet option is the most promising new feature. You just click on a tweet, expand the menu at the bottom of the screen, and choose ‘Speak.’ Seesmic then reads your tweets back in a frightening robotic voice, but it’s still a great idea. I’d like a Speak button to join the Reply, Retweet, and Favorite buttons at the bottom of the screen instead of having to expand the menu first. The feature seems like it would be most useful while on the road or when your hands are otherwise full, so less clicks is better.

Seesmic is a great way to tweet and check your Facebook feed and messages. Pick it up here in the Marketplace.
