Sean B. Palmer: "I fall into the trap of pegging a particular idea of requiring a certain level of QA and then not getting around to doing it because the extra work is offputting, even though releasing it at a lower QA and then bumping it up later would be much more valuable than keeping it to myself. I've not yet developed any reliable strategies for convincing myself to do that."
Dan Connolly: "Don't look for reliable strategies. Don't constrain yourself further. Just relax and release early and often."

Another fallacy that I often succumb to along those lines is that Technology Will Help; i.e. that all I need is a better CMS or a better publishing mechanism and I'll be much more likely to write. it might be true and the perfect editor/CMS/website/whatever might be just around the corner, but in the meantime... DanC is lucky enough to have someone operate his weblog for him.
Having said that, I'm quite content to roll my own software, and actually there has been a steady improvement in how comfortable I've been with blog publishing software since I've been through numerous iterations of deciding what I want.
