The Bible says we are to confess are sins to each other (James 5:16). I still visit Internet discussion boards. There I said it.
I don't do it to the extent I did previously, but I still check in to a few places. I've been a member of the CARM discussion boards since at least 1997. I think it was CARM's "Calvinist Corner" that I first participated in. Before the rise (and fall) of blogs (now trumped by Facebook and Twitter), I had periods in which I spent a considerable amount of time on CARM. I've been a moderator at least twice, but it came to the point in which I simply didn't have the time, nor the interest to keep up with it. I still visit there, but not nearly to the extent I once did.
Visiting Internet discussion boards is very similar to going to a certain "type" of antique shop: one second in the door you realize you've stepped into a disorganized collection of junk, probably very similar to a horder's basement, musty smelling, dirty, piles of this or that, broken stuff, and bizarre curiosities that demonstrate what humanity can produce. Every so often though, you find something of value or worthy of purchase (like my 1837 copy of Luther's Galatians Commentary). You've got to have the patience though to wade through a lot of junk. Sometimes what's junk to someone else you'll find to be treasure. Sometimes what you find to be treasure, everyone else thinks is a piece of junk.
That's sort of like what discussions boards are like. I was going to launch into a recent discussion board conversation I got myself into, but time has slipped away from me.
