Don’t you find it annoying, creating a free email address, only to find out the site has gone down after a month and will not come back ever? Same thing. Even if not permanency, then at least some consistency and reliability is expected of a reputable company such as Google.
Just because it doesn’t “sell” as much as you expect it to – all because you’ve only got eyes on your competitor – that doesn’t mean you just junk it. Doesn’t make sense. You keep eyeing Facebook users and ignoring the Google+ eager audience staring at you in the face (raises a bored hand, which is now down). What’s wrong with you Google people (squint). // End rant.
