Programmers don't have any concept of writer's block, when we can't think of anything else to write that is called a release. Ship it! (For personal projects anyway, commercial products ship way before that.) Programmers don't usually sit around and think, "What should I write for my next program?". There is a perceived need and if there isn't already a program to do it (reinventing the wheel is a no no) then a new project is born.
I take a similar approach with my blog. I feel the need to write something somewhere and poof there is a post. It is as much for me as for anyone else, probably more for me. For example I keep a list of add-ons I use in game here which I use to update my own add-ons. I also keep a list of the blogs I like to read, I bet there are tools or something to track blogs, but I just link them and use my own blog as a starting page of sorts.
So anyway, the best kind of writer's block I can think of is when you can't think of anything to write because the Big Bear Butt himself complimented you. That has to be like the druid blog Nobel prize. I'll be telling everyone I know for like the next month (at least the people who wouldn't look at me like I am crazy). The first person I told said, "holy cow, that's awesome!"
Haven't been nearly this excited since I saw the new druid forms and this is way better. It is probably druid heresy to say such things, but it's true.
