Data Privacy Day

Today is Data Privacy Day.  This was created so people would remember to think about their privacy for online sites, particularly in relation to social networking sites.  What does this mean for genealogists?  It is important to remember that what we put online can be seen by all.  If you have a genealogy blog, do not post information about living people unless you have their permission.  Remember also that what you put online will always be there, through Internet Archives' Way Back Machine, for example.  It is always better to be safe than sorry.
