Here’s my idea for a little OS X application, Twitter in the Finder Bar (of course, I would call it something better than that :P). As I’ve illustrated in the following image, this application would display the most recent Twitter post from your friends (vertically scrolling when a new one comes in) in the OS X Finder Bar.

Twitter is a service that is a perfect candidate to be condensed down into the Finder Bar’s small horizontal UI area. It’s out of the way enough to not add to clutter, but sitting right there for when you need it. Since Twitter’s content is made up of text no more than 140 characters in length, there’s really no need for an expansive UI.

To provide some interactivity, if the user clicks in the text area it turns into an input box, that is used to write a new Twitter update. For example, in this case I might click it and write a response to Todd: “@Todd Iron Man is great. Have fun!” hitting enter to post.

I came about this little idea since I really have no need for the relatively bulky Twitter GUIs that exist today. My Twitter needs are limited to seeing the latest update and being able to reply or add my own in a snap. The current available solutions have user interfaces that are far too involved for these simple operations, and take up too much screen real estate.

If anyone is, or knows anyone with the knowledge to bring this to life, and is interested in developing this small freeware app. Let me know.
