Is the Site Updated or Not?

When performing online research, do you keep track of whether a database is updated periodically or stagnant and fixed? FindAGrave and other sites are continually growing with new information and should be "rechecked" every so often. 

Other databases or sources are "complete" and unless you've learned new name variants or corrected details, period "rechecking" is not always necessary. One easy example would be a county history that has been digitized and put online. Usually once you have checked something of that type, you've checked it for good.
