I prefer to use no 3rd party tools at all, precisely because they are not part of the game. I've tried TS for Elite out once or twice, and met some very nice and friendly people that I had a lot of fun playing with.
Elite does include socialisation tools, and they do in fact work - but they are ignored by many as they do not currently work to the degree demanded by some (as it's based on friends list and proximity) - so off they go using 3rd party tools, and then ask why Elite doesn't have the same thing - completely ignoring the fact that Elite works on P2P island communications.
Fair enough, for me for example comm chat is difficult to use at the moment if I`m pinpointing the USS and cant grab the keybord. They could at least try to implement some sort of station chat.
