Mashable posted an article today outlining the oldest member of the Social Networking site, Facebook.

With almost a billion users on the Social Networking leader, the ranges in ages are growing. Most may be in the late teens and be glued to their computer screens all day and night, however there is a growth in the signups of other age groups, according to the Mashable article.

Now, a very old woman aged 101, named Florence Detlor is a member, and she was invited into the Facebook Offices for a little congratulations from COO Sheryl Sandberg, and the CEO himself, Mark Zuckerberg.

The post was made on Facebook by Sheryl on her Facebook page, and it has received comments from people who have grandparents aged 102 and 103. It would seem that Florence already has some competition.

She doesn’t look a day over 25. Congratulations, Florence.
