Barney's record is average. He has a good run with the Joys (some people collect badges...), surprisingly, but otherwise, hit and miss, much to his chagrin.

Yes he does. He has a tendency to treat the network like his blog since it's the closest thing to the internet. Much to everyone's annoyance sometimes.

Not yet.

Not on a network post, but it can be assumed he has done it a few times for people he's met in bars. Otherwise, yeah, he mostly hangs out with Larry and Larry has a girlfriend so...makes the game a bit harder.
