When Facebook launched their instant messaging system a while ago they knew it would be popular simply due to the masses of people who already call the site home, though it seems it was good enough that people are now ditching traditional IM programs like Windows Live Messenger, GTalk and Yahoo Chat.

Facebook’s engineers today revealed that FbChat is now serving over one billion messages per day. While that may not sound so phenomenal considering how many more the other big guns serve, though you should begin to take notice when you consider that the system is less than a year old.

So, will it ever take over from the likes of AOL Messenger? Probably not, but it’s still a massive leap for something that’s been around for such a short amount of time.

According to TechCrunch, Google is set to possibly purchase social media giant Twitter for a sum which could be in excess of $250 million. While reports are early, this news apparently comes from several credible sources which are all saying the same thing.

This comes after recent news of the attempted Facebook acquisition of the site for around half a billion, though it’s impossible to compare the two figures as Facebook’s deal included a whole swag of very overvalued stock. As Google’s bid would assumedly be cash-based, it would be worth much more on face value.

If the sale goes ahead it will be the second sale from the founders of Twitter to Google as the sale of Blogger went ahead only five years ago. Biz Stone and Evan Williams must have a mighty large smile on their faces right about now.

Whether it’s going ahead or not will only be told in the future, however it’s a good bet that someone will buy Twitter eventually. Our only question is, when will Microsoft put their bid in?
