Twitter now officially supports the cashtag, which sounds very close to Cash Cab but is actually way less fun. Going forward, you can click stock abbreviations with a $ sign in front of them to get financial information about the company.
For example, when you search $FB, you’ll see relevant tweets about Facebook stock doing poorly. Twitter isn’t the place you should go for monetary advice. Ever. And people frequently get these acronyms wrong ($APL instead of the correct $APPL, for example). But if you’re a finance nut, this could be useful if not kind of interesting. For everyone else, it doesn’t really matter. Who cares about hashtags anyway? [TheNextWeb]
