Ask HN: Do you think sites like Stack Exchange/Github have led to fewer blogs?

Someone asked today about what the point of blogging was for developers [0]. As I was thinking about it, I wondered whether or not new developers are choosing not to write blogs anymore in favor of a public Github and/or lots of activity on sites like StackExchange. I don't have any way to quantify this though - anyone have a guess or thought? It seems logical - what's easier: creating high quality blog posts consistently, or publishing the work you're already doing? So my guess is that yes, there are fewer people starting to blog.<p>Thoughts?<p>[0] https://news.ycombinator.com/item?id=6858905
