The Ancestor Hunt has done a fun new thing with twitter hash tags on Rebel Mouse.
Try this one: https://www.rebelmouse.com/genealogy/
Rebel Mouse #genealogy tag
There is also one for #familyhistory: https://www.rebelmouse.com/familyhistory/
It’s a really interesting presentation of twitter #hash tags.
