On Thursday, January 24th, 2013, Twitter launched Vine – an iPhone app which allows users to embed six second videos within their tweets. However, it hasn’t been a smooth launch for the service.

Just days after it first became available, a porn video was selected as one of the “Editor’s Picks”, causing a stir on the Internet.

A spokesperson for the company said: “A human error resulted in a video with adult content becoming one of the videos in Editor’s Picks, and upon realising this mistake we removed the video immediately. We apologise to our users for the error.”

In addition, questions have been asked about how people will use the service. A quick search on Twitter for “Vine” brings up a number of results, however some of the best examples include Chris Mandle, a freelance writer for NME, showing a preview of the magazine’s next issue and The Verge showed an unboxing of the Blackberry Z10.

While the shaky start and the similarities to Cinemagram may make it a difficult market to break into, the fact that Vine is owned by Twitter is already a big boost. Furthermore, there has already been some great videos posted to the service and it’ll be interesting to see what users can come up with in the future. Hopefully it won’t be too long before we see Vine start to branch out.
