I blog about my electronics project. It's public in that it's online and accessible but it is for me, both to ensure I think things through well enough to write them down coherently and to have a reference for decisions. I blog my work activities on an internal wiki for similar reasons. Major decisions need to be gathered in project documentation but small decisions and daily challenges are good to have written down.
