I have never used in conversation, but sometimes use it in writing. My native language has a gender neutral pronoun, so it did not take too much getting used to in English. You say the double usage of 'they' might be confusing, but in pratice believe it has been around for long enough on the internet that I have a high enough confidence that most readers will understand it's use or at least not be too distracted by it.
