* '''Write professionally.''' Blog postings are less formal than other types of writing, but they are still a reflection of your communications skills.

* '''Remember that the internet has a long memory.''' The Planet page is generated periodically, and even if you delete or change your posting, it may be indexed, cached, or reposted until the planet is re-generated. Avoid saying something that might come back to haunt you later -- and remember that future employers may read your old postings (as well as future in-laws, office mates, and so forth).

* '''Do not use profane, obscene, or rude content, or content that belittles other people.'''

* '''Do not link to profane, obscene, rude, or illegal material or to sites that knowingly violate intellectual property rights''' (warez).
