Former Google staff member reveals the companies failures

Developer Chris Messina is a former Google staff member and he says the company has "really f---ed up".

Mr Messina, who invented the hashtag, spent three years helping create Google+ and has written a blog about the failures of the corporation.

Mr Messina, who left Google over a year ago, details in "brutal honesty" how he believes a lack of innovation by the technology company has left it behind.

He said Google+ was supposed to create a trusted base for users to share information with a selected group of people, but the original concept for the platform merely became a copy of Facebook.

“What’s sad to me is that the promise of Google Me (the original name for Google+ internally) could be found in launch post: ‘We want to make Google better by including you, your relationships, and your interests’,” Messina wrote.

Instead, he says it became a kind of “Facebook-lite”.

“Why did the world need another Facebook, unless to benefit Google by making their ad targeting more effective?”

Messina says he is ashamed that he spent years on something he believes will become pointless.

He does, however, want Google to succeed and believes they have enough resources to do so.
