If you haven’t worked out how to have fun on Twitter by taking part in games and meeting likeminded gamesters then MumbleIt could be a good place to start. MumbleIt takes advantage of the way keywords can be used on a website and Tweeted, or vice versa, so that Twitter users can join together to collaborate in joking discussions.

To do this you log in on the MumbleIt page, and this uses your Twitter login details. You can also take part on the MumbleIt webpages anonymously. The idea is to come up with topics that will get other users posting brief comments or pictures, and the posts are automatically posted to Twitter so all your followers can join in or see what’s happening. I couldn’t quite see how interactive this was but my start posts were definitely Tweeted.

MumbleIt also lets you upload pictures so a topic could ask for photos rather than comments, or both. For example, one of the popular topics is ‘Show me your refrigerators!’ which has a surprisingly intriguing set of fridges photographed and revealed by other Twitterers. ‘Useless Facts’ also had a number of people joining in, and the person who started it used the hashtag to make it an easy-to-find trending topic on Twitter, as #uselessfacts.

I tried it out by starting a topic called #MyChihuahua and put a photo of my own dog. When I looked later my topic had become popular with other MumbleIt users posting comments and photos of chihuahuas. These were very comical and I recommend having a go. Along with Artwiculate.com which I reviewed a while ago, and still play every day, this is a great example of how Twitter can work with an application to get people making friends and having fun together.
