by what you wrote: "... some people don???t have the common sense to pass on information naturally." This tells me you are a writer/communicator who works with other writers/communicators. I can tell you it is not some people that don't have good communication skills - it is MOST people that don't have good communication skills.

Everybody wants more communication - but only in their preferred medium (f2f vs email vs daily/weekly/etc status reports vs whatever). Everybody wants to receive clearer communications - whether they can communicate clearly or not. Everybody wants to have input to the project/process/issue/event - even if their input is not needed, desired or of value. Too many people want to be "irreplaceable" on the job which leads to a natural tendency to "hoard" information, especially about what they are doing and how - even if someone else has a need to know because they share work or their work is dependent on the hoarder's.

But I do have to agree that "Alone-in-the-World Syndrome" and "Read-My-Mind Syndrome" are real. And apparently contagious.
