I agree with the OP. It interferes with communication. And since it's also an obstacle on the other player's end, I assume the effect is doubled. It's one of the things in the user interface that I am waiting to see changed (among other things) before becoming a paying member.
The OP may have a good point, but I want to mention that if you become a paying member you won't see any ads,
"I'm just saying"
The pop up that comes at the games completion is making me rude. I always like to type something at the games conclusion to thank signify we are people, something, usually just good game. But the pop-up always takes me to another page. This was added a few months back. Now I find myself just leaving because when i hit enter to send the message it opens a new page. I understand advertising, but this borders on that trick gimmick stuff that people hate so much.
