Only God can be present everywhere; if I try, I'm being self-idolatrous and unrealistic. Neither does it make sense for me to try to carefully budget my every social resource and manage the lives of others. God will do what He wants in and through me and others, and He's capable of more than I've been willing to believe or allow. Somewhere between the two are limits that are appropriate. It just makes sense to accept that.
That means opting out of some rabbit trails and not looking for online interaction to meet my personal needs. It's scary how much I've let both problems become characteristic of my internet life. And I do think I can continue to give and receive a great deal online—being more intentional will, in some instances, mean more interaction. But when my internet activity leaves me too drained or cynical to engage other parts of my life, or becomes a place where I'm craving some kind of response from others, or if I find myself trying very hard to project or preserve some kind of image, it needs some adjustment. That likely isn't something anyone but me would notice, anyway. And so far, those realizations and subsequent actions have been a help.
