On the other hand, writing about your work may actually help you take it further, as it forces you to organize things in your head (a bit like rubber duck problem solving). That's my experience, at least.

Blogging should not be seen as an act of procrastination. Unless this act is occupying the whole day, the whole week. Blogging is a sane act of self development or this is how I see it. Most people lack the skill to communicate properly and blogging can be a potential tool for any entrepreneur and hacker.

To anyone who is doing a startup, blogging can be an interesting exercise in general communication. Blogging, in short words, will make you become a good storyteller. You will develop your communicative self so you describe anything in a pleasant manner and it will help outline greatly any part of your project.

I read many texts and business plans (in spanish) and they are pretty boring most of the time because the team has a big lack of writing.
