Scott encourages folks to start their own blog, especially developers:

“You are not blogging enough. You are pouring your words into increasingly closed and often walled gardens. You are giving control – and sometimes ownership – of your content to social media companies that will SURELY fail. These companies are profoundly overvalued, don’t care about permalinks, don’t make your content portable, and have terms of service that are so complex and obtuse that there are entire websites dedicate to explaining them.”

It’s true that the world today is about social networks such as Twitter (ugh) and Facebook so to reach more folks, I simply post to my blog and then link to it on my Facebook wall.  Best of both worlds!
