A big chunk of the time I spend on Facebook involves groups that discuss local history. Some are related to schools I attended, some are "I Grew Up In [neighborhood, city, county, region]." Some have the word "history" in the title (e.g., Northern Virginia History). Some are about the local music scene in years past. All of them tend to have a lot "who remembers thus-n-such" posts and pictures from the past. I'm into local history and have lived here all my life, so I enjoy these and participate in the conversations. I'm a member of probably 5 or 6 of these and am aware of others that I don't join because they're redundant. Obviously there's a lot of overlap in subjects between the groups. I have to assume these are common across the US and probably other countries, no? I'm curious as to how many TGP'ers participate in these.
