It seems Facebook has changed some of its programming yet again. Numerous pages have had their "Likes" dropped from inactivity. I, unfortunately, have also fallen victim to the new programming.
If you haven't done so yet, please head over to Jerri's Empty Nest on Facebook and give it a "Like" when you have a chance.
If you already have liked the page, please head over and make sure yours was not one of the likes that was dropped. If you still like the page, remember to "like" the individual posts that you enjoy. This interaction with the page will ensure that your "Like" of the page will remain active.
