There is this service called Tweet cloud, which analyses your tweets for keywords and creates a cloud with the most highly used ones. Pretty. interesting too. However, I find that when it posts a link to your cloud, it also posts an image of the cloud using twitpic. How does it login to twitpic to post on my behalf?
Here’s the process.
When you login to the website, you reach this basic page, where it tells you about the service. Clicking Generate a cloud prompts you to grant access with your Twitter account.

So I suppose the question now is if Twitter authorizations can be used by third parties to post in my name. Sure, this time, nothing offensive as such was done, but the point that it is possible to do it – is it a security issue? You decide.
