The use of twitter as legitimate micro-blogging platforms requires that twitters should adopt certain basic principles of twitter ethics. However some of principles pertaining to twitter ethics can be found evolving at the time of publishing the present website.

(Note: use Twitter however you want. These are just some serving suggestions.)

Use an avatar. It lets us know you're possibly human.

If you're using Twitter only as a link feed, consider marking your "bio" section with that, so people can decide.

If you don't have much to say, it's okay not to say it.

An @ message at the beginning of a post shows up in replies. Further in, it doesn't.

It's okay to promote yourself. Just consider promoting some other folks, too. Mix it up a bit.

You're not obligated to friend everyone back. Some people use Twitter differently.

Removing someone as a Twitter friend doesn't (necessarily) reflect on how you feel on them as a person. It's okay.

Don't let other people tell you how to use Twitter. (Get it?)
