Dive deep into research... Or write around the block. By that I mean, if I find that the starting point of a post is difficult...I'll write from the middle to the front, then finish up, basically. Or while working on my other writings, I usually have an outline, so what I do is skip the scene immediately in front of me and work on the scene immediateyl behind it. That generally works, since it lets you attack the problem of writers block from, basically, two approaches, nipping away from both the start and end points. 

The only problem is that sometimes it's a slow and painful process...and sometimes energy-intensive in my experience. But it usually works pretty well.
