Wish you could have the Facebook Messenger experience somewhere other than your mobile device? Pine no more because now it's available on the web (it's a platform now, remember?). As Slashgear notes, it's essentially the app experience but living inside your browser. Simply head over to Messenger.com, sign in with your Facebook account and you're good to go. Folks who've been IM'ng from within Facebook proper will probably welcome the change, but if you're using a standalone client the likes of Adium on Mac or Pidgin on Windows you might be wondering what all the fuss is about. Sadly, it doesn't look like one of the mobile version's cooler features -- chat heads -- have made the transition just yet.
