Twitter Tuesday: Twitter for Mac lets you tweet from anywhere in OS X, Tunisian revolution gets tweeted

Hey, Twitter fans! You may remember a debate that sprung up last year about whether Twitter makes an effective tool for social change and grassroots organizing. Well-known author and New Yorker columnist Malcolm Gladwell said no, and Twitter founder Biz Stone wrote a rebuttal defending the service's usefulness to activists.

Well, at least one revolution has now been tweeted. Tunisia, the northernmost country in Africa, has forced out its president and called for a new election. The "Jasmine Revolution," as some are calling it, was tracked live around the world on Twitter. It's never been this easy to follow the events and voices of a large-scale political protest without a news station acting as a middleman. I'd say that's one point to Twitter for changing the way we experience world events.

On the other hand, as Martin Bryant points out at The Next Web Middle East, the real-time nature of Twitter makes it impossible to read everything when the tweets are coming as fast as furious as they were on #sidibouzid, the Tunisian protest hashtag. Also, popular hashtags attract spammers, further muddying the waters. Twitter's speed is a double-edged sword at the moment, so it's probably good that we still have traditional media around to filter the massive firehose of news tweets until there's a smarter user-controlled filtering system.

Tweet From Anywhere with Twitter for Mac

Twitter for Mac has become quite popular since it debuted in the Mac App Store a couple of weeks ago, but one of its best features wasn't publicized until recently. As Download Squad's Sam Gibbs explained earlier this week, Twitter for Mac adds a service to OS X that lets you tweet from any app just by selecting something and right-clicking.

Don't Know Where to Go Out Tonight? BarBird Collects Tweets from Bars Near You.

Yeah, it's only Twitter Tuesday, but Friday night is just around the corner! If you're the type to hit the bars, you might want to do so with the free BarBird iPhone app in your pocket. BarBird aggregates the Twitter accounts of different bars, and it's location-aware -- that's a powerful recipe for finding events and drink specials near you. You can even filter down the results so you only see tweets about discounts, happy hours or drink specials. Just remember to be safe when you go out -- don't drink and tweet!

Oh, and if you're not an iPhone owner, you can still use BarBird's web interface.

Well, that's all for this week in Twitter. It wasn't the most eventful seven days on the Twitter app front, so here's hoping for some major Twitter client updates next week to get 2011 off to a good start.
