Sometimes you can’t be there in person to present your pitch. Making the pitch on the phone works, but it lacks the visual punch that a stellar presentation offers. Fortunately, technology can help.Next time you have a presentation that you need to present remotely — or don’t want to lug your laptop around and know that you’ll have a network connection — consider using a service such as Slideshare. If you’ve used YouTube, Slideshare will feel familiar and comfortable. You can upload presentations created in PowerPoint or OpenOffice to Slideshare and then add tags and tools for discussion as well as imbedding tools for animations and other multimedia. By sharing your presentation across a network, you can virtually leap across geographic distance and the Web 2.0 communal component may open up new opportunities for collaboration that you’d never considered.
