Are All Your Genealogy Eggs in One Basket?

Are you putting all your genealogy eggs in one basket?

Do you only use one genealogy website?

Do you only post your information (if you choose to post it online) on only one website?

Do you only post queries to one website?

If that one site goes "kaput" for whatever reason, what happens to the information you have submitted to it?

Is it time to get more than one basket?
