I was never a member of OxGoss, but I lurked and read posts fairly often, and I remember working out Sir Peter Parker's real life identity (if I'm correct, he studies the same subject as me, but in the year above) and finding it very hard to restrain myself from referring to him by his internet pseudonym whenever he was mentioned by friends who knew him...
I kind of resent the demise of OxGoss - it was truly hilarious how basically everyone on there was an interested party of some kind or another. Threads in the Union and journohacks' fora especially tended to just degenerate into slate v slate/Cherwell v OxStu bitching, and it was brilliant to read.
