When I saw in first time what Twitter remove 140 character limit I don’t believe in this at start. It’s cool move. Now you can send a full length messages to your friend and Twitter become a real message app. Surprise for WhatsApp, Viber and etc.
But no changes about public twit messages – the will have 140 character limit as usual. So, maybe in nearest future Twitter change own strategy and also remove 140 character limit from all messages in service. It will be cool time, bro!
