While undirectly related to your post, Me and one of my contributor have pubbed a post about blogging that might interest you. There’s a link in it that points to a list of tips helping people overcome the writer’s block.

I personally find that dabbling a bit on one idea and then a bit on another topic depending on my whim can be helpful for me. Sometimes I get inspired to write about a topic and sometimes just putting the title of it is enough so that at least I’ve got an idea for a future posting. When I feel like it, or during off times, I do go back to these unfinished postings and start writing. Normally, I don’t finish an entire posting in one sitting but rather over several sittings. For me, this keeps things fresh and not so boring and monotonous. And of course, if I get an idea, I can then put it down. That’s normally how I write my postings. They’re usually unfinished with contributions done at odd days and times, which eventually gets done.

Sometimes, just getting out of the house and doing something else and away from the computer can help me get inspired to write again.

Not really a solution, but this is what works for me.
