The festival comes on the heels of a global twestival in February that drew the participation of 202 cities across the globe, including Jerusalem. This time, the meet will have a decidedly local flair, as part of the worldwide Twestival Local initiative, which aims to have each city put on its own event between the 10th and 13th of September. While the February Twestival helped raise money for clean water in the developing world, this time users will twittering for a cause a bit closer to home. Tech Career, a startup that helps get Ethiopian immigrants to Israel into the country's booming high-tech industry, will be the benefactor of the tweeters' largesse.

The Twestival will take place, appropriately enough, at Jerusalem's Bloomfield Science Museum, and will feature guided tours of the museum, wine tastings from boutique Israeli wineries, bagels and screenings of the Steven Spielberg Jewish Film Archive footage of the Ethiopian aliyah in the 1990s. And of course, there will be every social media activists favorite activity - live tweeting, blogging and broadcasting, with a healthy dollop of social and professional networking bound to come about.

While the social media community is Israel is dominated by Anglophones, the festival is open to immigrant, sabra and visitor alike. Even those who've never used the application but want to learn more about it are encouraged to join in. Organizers said they expect 75-100 participants, up from the 61 people that showed up at the February meet.

Charlie Kalech, director of J-Town, which does Internet consulting work, is organizing the event. He said twitter is especially suited for this type of meet because of its ease, brevity and conciseness, which makes it popular as a professional tool and among "grown-ups." To that end, there will also be tweetorials at the event, to show users how to get the most out of their microblogging. And the whole shindig is all volunteer-run, by the local twitter community, which will now get a chance to meet face to face.

"Part of the idea with the event is to do something that's grassroots, 100 percent volunteer," Kalech said. "It's by the community for the community. It happens quickly. Let's do something, lets make a difference."

The Twestival will take place from 8-10 p.m. on Thursday, September 10. NIS 50 gets you in the door.
