I just noticed a Twitter virus
twitter.com
It spreads when someone hovers over the text on their web-based timeline. It does not appear to spread in search results or individual tweet page.
e.g. http://twitter.com/ibackupyourshit/status/25112187461
twitter.com
e.g. http://twitter.com/ibackupyourshit/status/25112187461
It also makes the text so big that as soon as it appears in your twitter feed its impossible to avoid mossing over it.
Nothing is happening. I created an isolated twitter account to try it, and nothing.
