About plugins being outdated: I do not agree that the list is outdated if I stop using some of the plugins on my blog. I still use only the plugins from that list, but I have removed some of them and done similar functions by coding (like Tweet this etc) and I have blogged about how to do that.

And about not writing about blogging: Writing a post on post byline may not seem to be exactly relevant to your blog but it is still info that may help you improve it. When you start getting visitors then small changes can improve your conversion rates.
