Stop finding excuses and start writing on your blog and web site. Find interesting topics your audience will be interested it. Here's post I found with a quick lesson on writing good captivating stories/posts people will want to read Say Nothing In 500 Words  

Here are a few samples.

Avoid the obvious content."Say the assignment is college football. Say that you've decided to be against it. Begin by putting down the arguments that come to your mind. Now when you write your paper, make sure that you don' t use any of the material on this list. If these are the points that leap to your mind, they will leap to everyone else's too. Be against college football for some reason or reasons of your own. If they are keen and perceptive ones, that's splendid. But even if they are trivial or foolish or indefensible, you are still ahead so long as they are not everybody else's reasons too."

Get rid of obvious padding. "Instead of stuffing your sentences with straw, you must try steadily to get rid of the padding, to make your sentences lean and tough... You dig up more real content. Instead of taking a couple of obvious points off the surface of the topic and then circling warily around them for six paragraphs, you work in and explore, figure out the details. You illustrate."

Getting started is the hardest part.
