I have used internet since 1990. I’m not the first user, but it was in a time where the community was small enough that the community was able to give recommendations and help on how to use correctly technologies such as email, usenet, etc.
The internet grew tremendously. Email traffic exploded (more than 90% of spam). The Web enabled a lot of interactions by masking different communication modalities. Many have no idea what is the Netiquette. And maybe it’s fine.
Each W3C mailing-list is a small community with most people being engineers. It is often surprising to see top posting (replying on the top of the message and leaving the full thread quoted), or putting one line comment in a long quoted message. There are better ways of using emails.
- Just quote the appropriate part of the message and reply under this quote
- Do not top post
- Be careful to keep author of the quoted message
- Write short messages in high traffic mailing-lists
I recommend everyone to read the Netiquette. It might be old school, but most of its principles still applies.
