Bruce McCormack (Charles Hodge Professor of Systematic Theology at Princeton Theological Seminary) wrote this on FB about the utility of reading blogs. I reproduce it with permission:
There was a time, not so long ago, when theological blogs had the capacity to educate, to push the boundaries in a healthy way, to teach me what the new generation was thinking and how best to address them. But I fear we have reached a turning-point. Now bloggers tend to confuse earnestness with seriousness. Seriousness distinguishes itself from mere earnestness by the degree of its responsibiity to a subject-matter. An earnestness which lacks this is purely an exercise in self-performance, an exercise in banal speech which communicates next to nothing. The avant-gard is losing its capacity to teach in its self-absorption. And it making itself increasingly irrelevant to church life.
