Cool that you're interested in the story, because there are quite many storys about all this. You have read the most fundematal parts already.
Mine is that I got sad because a TGP member I highly respected and looked up to suddenly was gone, and a bunch of what I consider forum friends alerted me to what happened. Then some of them started to drop out. Then I got an invite here early on, but waited a few weeks contemplating why I want to be on two idiot forums dealing with idiots. But yeah, I came here and felt better. Im still active on TGP though.... there's some really nice and great people over there. For me it's worth checking in there sometimes. But this is home.
