10) Remember that the "like" button is not a measure of virtue. You may have hit a nerve. You may have affirmed thousands of people in an opinion that they already held. Or you may have challenged millions to change their lives. The last of those three alternatives is a long shot. The internet is an undifferentiated marketplace, filled with quality merchandise and junk. Its consumers include connoisseurs and junk dealers. Tell the truth, post with care, and trust the results to God. (That, after all, is one thing that hasn't changed in the digital age.)
11) Live at the top of your form. As hard as it is to think of it this way, think of the internet as the opportunity to cultivate wisdom and charity. We have the rare opportunity to talk to more people at one time across time and space than anyone imagined (except our grandchildren). Use the gift wisely.
