ONCE the province of historical societies, museums and library archives, a new wave of nostalgia is gripping social media.
From Lost Brisbane to Lost Darwin and Lost Hobart - and a heap of "lost" geographical regions in between - Facebook nostalgia pages are hugely popular.
My absolute favourite is "Have you seen the old Gold Coast" with its unashamedly kitsch and retro photos from the holiday destination's glory days. There's photos of "Vita-Tan" sprayed on sunbathing bodies in the 1960's (in the days before melanomas) and photos of Sammy the Seal at the Porpoise Pool.
The page has 22,500 followers and was started by 59-year-old Southport local, Karen Wright whose family are 6th generation "Goldies".
"We were one of the pioneering families. There were photographers in my family, so I had all of these photos locked away in the cupboard and in boxes… I thought, why not share them?" Karen said.
The page has amassed 15,000 photos shared by fans and historians now seek our Karen's help with research.
"Sometimes a library or museum will send me photos they are researching and within minutes of putting them up on the page, someone will have identified the place or people in the photos."
While Karen's page is reuniting Gold Coasters online, one Sydney nostalgia page, "You grew up around Hornsby if you remember . . ." had 9000 "likes" within two weeks and led to a reunion at the local RSL Club so that members could relive their youth, with at least one teenage romance rekindled.
Search Facebook and you never know what (or who) you may come across.
